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).
- Closes#9486
- All tests are succeeding or marked pending
- Created follow up tickets for things that still need to be addressed, including:
- Fixing upload / table update #10609
- Fixing `Count_Distinct` on Boolean columns #10611
- Running the tests on CI is not part of this PR - to be addressed separately
- Part of #9486
- Fixes `Table.union`, `merge` and `distinct` tests
- Replaces `distinct_on` in `Context` that was actually a Postgres specific addition leaking into the base with a more abstract `Context_Extension` mechanism.
- This allows us to implement the Snowflake-specific `DISTINCT` using `QUALIFY`.
The `System.exit 42` component is treated the same way as any other Panic error - it does not interfere with other component evaluation:
After removing the `System.exit 42` component, the workflow works as expected. I have also tried opening the project with the component and then removing it.
Enables `engine.TruffleCompilation` in `std-benchmarks`, collects the logs and dumps compilation into to `System.err` when a benchmark is influenced by dynamic compilation.

- Batching of expression tests
- Fixing arithmetic by simplifying `%` and `/` operations
- Trying to share some more tables, sometimes improving performance sometimes not really
- Adding sorting and other fixes to tests to make them pass: Missing_Values_Spec, Filter_Spec, Map_Spec
- Fixing warnings related to materialization of Decimal->Integer, thus fixing Join_Spec.
- Related to #9486
- Ensures that even though an integer column in Snowflake is represented by `Decimal` type, if the values are small enough, they are materialized as `Integer`.
- If the values are larger, they are still read in as `Decimal`.
- Adds tests for some other `Decimal` edge cases (various precisions and scales), and for `Float`.
Fix#10503 by creating a benchmark and then speeding it up by making sure usage of `InteropLibrary` reminds in partially evaluated code and isn't hidden behind `@TruffleBoundary`.
- 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.
- Removes `First` and `Last` from the `Standard.Base` exports.
- Enable auto-scoping for all `Index_Sub_Range` and `Text_Sub_Range`.
- Update all use of those methods to use auto-scoping.
- Remove publishing the constructors.
- Fix any missed use in libs.
- Alter tests to generally use auto-scoped calls.
- `on_incomparable` to `on_problems`.
- Rename `Location.Start` to `Location.Left`.
- Rename `Location.End` to `Location.Right`.
- Use auto-scoping for `Location`.
- Tune widgets for `Text.trim`.
- Correct signature of `Text.split`.
- Adjist `generateLocallyUniqueIdent` to not fail on bad signature.

- Part of #9486
- Fixing our tests to not rely on deterministic ordering of created Tables in Database backends
- Before, SQLite and Postgres used to mostly return rows in the order they were inserted in, but Snowflake does not.
- Fixing various parts of Snowflake dialect.
- Removed `second_row` and `second_column` from the `Table` and `DB_Table`.
- Added `first_value` and `last_value` to the `Table` and `DB_Table`.
- Fixed bug where negative index access wasn't allowed on `Column`.
- Added error if negative index access used on `DB_Column`. Tells user they have to materialize.
- Fix argument order for `Table.text_cleanse` and a couple of typo corrections.
- Rename `auto_value_type` to `auto_cast` on table and columns.

- Includes HTTP method in error message
- Does not do special handling for `403` status code - this was wrong and led to `Unauthorized` error when the real cause was lack of permssions in the Cloud. The errors should be more understandable now.
- Adds `projectSessionId` to audit log metadata.
- Fixes a test (`Secrets_Spec`) that did not have unique names and would fail if cleanup of previous runs failed (or if ran in parallel).
- remove legacy matrix and object types from vue component and any further code relating to those
- remove the index and index header being sent in the json for tables
- add has_index_col flag for json hat previously sent 'indicies_header' and 'indicies' so that index/# column is still rendered where required
- Part of #9486
- Building on top of initial work by @jdunkerley and finishing it
- Reverted the changes to the Postgres_Dialect from last Snowflake work and split the Snowflake_Dialect into a separate module.
- Moved from `rounding_decimal_places_not_allowed_for_floats` to `supports_float_round_decimal_places` (as too confusing).
- Added Snowflake_Dialect type.
- Extracted `Snowflake_Spec` into separate `Snowflake_Tests`
- It imports the common tests from `Table_Tests`.
- Some initial adaptations to make the snowflake dialect not-crash.
- Adding `Internals_Access` proxy to allow external implementations to access our internal data structures without directly exposing them to users. Users should not use these.
- Adding profiling of SQL to check performance.
