- Fix any issues identified by the doc writer.
- Alter all `default_widget` functions: all now take display and all use the type check signature.
- Review widgets on AWS APIs and make sure display is correct.
Replaces the Regex based number parser with a new parser which works out the same by working out each part as it sees and example of it.
Close#7398 - performance of reading the large CSV now about 2s (down from 15-20s).
- Part of #11311
- Adds ability to read a list of files (Vector, Column, Table) into a Vector.
- Reading into a Table of objects or merged will come in a next PR.
The ultimate goal is to reduce the method calls necessary for `Vector.map`.
# Important Notes
- I managed to reduce the number of Java stack frames needed for each `Vector.map` call from **150** to **22** (See https://github.com/enso-org/enso/pull/11363#issuecomment-2432996902)
- Introduced `Stack_Size_Spec` regression test that will ensure that Java stack frames needed for `Vector.map` method call does not exceed **40**.
Once our libraries and tests are compiled with basic inference of method types, some warnings were reported:
```

This PR attempts to fix them.
There was also an expected error in the Examples:
```

```
To avoid getting a warning, I wrapped this in `(_ : Any)` to make the warning go away. The behaviour of the function is unchanged.
- ✅ Alter default `Any.pretty` so constructor is prefixed with type name (as needed now).
- ✅ Tests for `pretty` on `Date`.
- `pretty` for ✅ `Date_Time` and ✅ `Time_Of_Day` improved to not have as much noise.
- `pretty` for ✅ `Period`, ✅ `Date_Range` and ✅ `Range`.
- Added custom `pretty` for ✅ `Vector` and ✅ `Array` as built-in method doesn't call through to overrides.
- Added custom `pretty` for ✅ `Column` and ✅ `Table`.
- Bug fix for `pretty` in `Time_Zone` so calls through to `pretty` of the zone_id to ensure safely escaped.
- Initial `default_widget` for `Date` and `Time_Of_Day`.
- Improve widget for `Date.to_date_time`.
- `to_text`, `to_display_text` and `pretty` for `Enso_Secret`
- private constructor for `Enso_Secret` as can't be correctly built directly.
- Use `_` for the testing methods in `HTTP` to clarify they shouldn't be used in general code.
Move annotations into fields of Function and ConstructorDefinition.
# Important Notes
New syntax: Constructor argument-definition lines
- Each argument in a type-constructor definition may be specified on its own (indented) line.
Relaxed syntax: Unparenthesized arguments to annotations
- A generic annotation now uses the rest of the line as its argument expression; the expression no longer needs to be parenthesized.
Add tests for coalesce and fix the In-memory version
# Important Notes
The distribution/lib/Standard/Database/0.0.0-dev/src/Internal/IR/From_Spec.enso change isn't actually needed for this MR as I switched away from using literal tables for these tests as trying to mix 2 literal tables doesn't look to be supported. The change I added will let any future developers know that.

- Make example render in mono space font.
* Add today, now and time to Expression.
* Move running and compute into Column as that allows them to be used in expressions.
* Fix bug.
* Fix exports.
* Java fmt.
This implements `DB_Column.with`, which uses `WITH ... AS` SQL clauses to remove duplicates in the generated SQL.
After a discussion with @radeusgd, we concluded that we will probably want a more complete CTE implementation, so this one is useful for now to deal with big queries (like `round`).
# Important Notes
Still to do in this PR:
- [x] Rename `with` to `let` (or something similar)
- [x] tests
- [x] documentation
- [x] remove `State` hack by moving query generation into a class and using a `Ref` field for scoping

- Closes#10411
- Also a similar technique allowed to add partial support for SQLite as well.
- Only `include_nothing=True` case is still not supported as the technique used for Snowflake did not port well to SQLite and I did not find yet a satisfactory workaround (it is doable, but too ugly to justify it for now IMHO).
- Enables the `..` autoscoping style for creating Atoms in expressions.
- Add type checking to methods in columns.
- Auto wrap returns from method in expressions into a column as needed.
- Remove `Time_Period.Day` to remove confusion..
Fixes#10609 by rewriting all our upload-related operations to rely on `DDL_Transaction` - an abstraction that handles 'transactionality' of `CREATE TABLE` statements dependent on if a given backend allows DDLs within transactions or not (if not it emulates transactionality by creating the tables outside of transaction and then dropping them on rollback).
- Adjusted Filter_Condition removing keep/drop from basic filters.
- Fix Is_In to have selector.
- Fix for Date simple expressions.
- Add get_row to Table and DB_Table.
In a sequence of value-level operators, whitespace does not affect relative precedence. Functional operators still follow the space-precedence rules.
The "functional" operators are: `>> << |> |>> <| <<| : .`, application, and any operator containing `<-` or `->`. All other operators are considered value-level operators.
Asymmetric whitespace can still be used to form *operator sections* of value-level operators, e.g. `+2 * 3` is still equivalent to `x -> (x+2) * 3`.
Precedence of application is unchanged, so `f x+y` is still equivalent to `f (x + y)` and `f x+y * z` is still equivalent to `(f (x + y)) * z`.
Any attempt to use spacing to override value-level operator precedence will be caught by the new enso linter. Mixed spacing (for clarity) in value-operator expressions is allowed, as long as it is consistent with the precedences of the operators.
Closes#10366.
# Important Notes
Precedence warnings:
- The parser emits a warning if the whitespace in an expression is inconsistent with its effective precedence.
- A new enso linter can be run with `./run libraries lint`. It parses all `.enso` files in `distribution/lib` and `test`, and reports any errors or warnings. It can also be run on individual files: `cargo run --release --bin check_syntax -- file1 file2...` (the result may be easier to read than the `./run` output).
- The linter is also run as part of `./run lint`, so it is checked in CI.
Additional language change:
- The exponentiation operator (`^`) now has higher precedence than the multiplication class (`*`, `/`, `%`). This change did not affect any current enso files.
Library changes:
- The libraries have been updated. The new warnings were used to identify all affected code; the changes themselves have not been programmatically verified (in many cases their equivalence relies on the commutativity of string concatenation).
- Related to #9486
- Fixes types in literal tables that are used throughout the tests
- Tries to makes testing faster by disabling some edge cases, trying batching some queries, re-using the main connection and trying to re-use tables more
- Implements date/time type mapping and operations for Snowflake
- Updates type mapping to correctly reflect what Snowflake does
- Disables warnings for Integer->Decimal coercion as that's too annoying and implicitly understood in Snowflake
- Allows to select a Decimal column with `..By_Type ..Integer` (only in Snowflake backend) because the Decimal column there is its 'de-facto' Integer column replacement.
