* fix: don't instantiate dummy fields for external types
For ANSI C compatibility reasons, we add a dummy field for memberless
types defined in Carp (see commit 59ef5bbf2b). When registering a type
with no fields, `(register-type A [])`, we'd also attempt to set our
dummy field in the Carp generated initializer for the type. However, the
registered type is totally opaque from the perspective of Carp, and we
can't assume it has a field corresponding to our dummy field.
This commit changes our handling of __dummy in initializers to avoid
setting it for registered types.
* feat: automatically implement str and prn for registered types
This commit makes the auto-generated str and prn functions for
registered types implement the str and prn interfaces, removing the need
for users to call implements on these functions explicitly.
It alters the signature of `autoDerive` in Primitives.hs slightly to
make it more flexible (since registered types have no delete or copy
functions that we can add to the implementation lists of these
interfaces).
* docs: add docs on register-type to CInterop.md
The new documentation clarifies the usage of `register-type` and accounts
for the changes in the prior two commits.
* fix: fix function signatures for generic memberless initers
Filter out dummy field arguments.
* docs: Add details about type name overrides to CInterop.md

These macros apply an operation to the current value of a variable and
then set the variable to the result of the application. They are
effectively sugar for writing `(set! <var> (<op> <var> <val>))` and
should be familiar to those who have programmed in imperative languages
like C.
In Carp, all the underlying operations these macros use are interfaces,
so one can flexibly use them for more than just numeric types.
Example usage:
```clojure
(let-do [dial 0]
;; crank it up to 11!
(while-do (dial < 12)
(++ dial))
dial)
;; expanded
(let-do [dial 0]
;; crank it up to 11!
(while-do (dial < 12)
(set! dial (inc dial)))
dial)
```
This commit builds on the emit-c feature by permitting C typed values to
be used anywhere in Carp code.
For example, if one wants to use the literal C macro `EDOM`:
```clojure
(register EDOM C "EDOM")
(Int.+ 1 EDOM)
=> 34
```
when compiled, this will produce the call:
```c
Int__PLUS(1, EDOM)
```
So it provides a quite flexible means of using C macros directly. It is,
of course, also radically unsafe. Anyone registering and using values of
the C type better be cautious.
One can get pretty crazy with this feature:
```clojure
(register comment-it C "// commented out;")
(Int.+ 1 comment-it)
=> int _11 = Int__PLUS_(1, // commented out;)
int* _12 = &_11; // ref
String _13 = IntRef_str(_12);
```
This commit fixes issue #1302, whereby types defined in modules were not
recognized as valid member types by our validation routines.
We simply need to account for types defined in modules in the global
env, threading the global env along through validation (previously we
only passed the top-level type env, which contains no modules).
A call to sequence in our handling of polymorphics would result in
discarding legitimate interface implementation results in rare cases.
Calling rights instead fixes the issue. We also need to take the union
of the results to ensure we account for cases such as polymorphically
realized interfaces (e.g. the `prn` function for a (Maybe String), other
wise, we don't resolve to concrete polymorphics for types that have
ad hoc polymorphic members.
Fixes#1307
* feat: Add additional ignore macros
This commit adds two new ignore macros, ignore*, which wraps an
arbitrary number of forms in calls to `ignore` and ignore-do, which
wraps an arbitrary number of forms in ignore, then bundles the whole in
a do call, effectively executing each form only for side effects and
ignoring all results.

* refactor: refactor concretize module
This commit primarily refactors the concretize module, breaking out the
local definitions for visit functions into top level functions that are
hopefully easier to change. I've also modified some monadic code in the
interest of terseness.
This commit adds some additional patterns for XObj forms as well.
* refactor: Only export called functions in Concretize
Adds an export list to Concretize so that the module encapsulates those
functions that are only used internally within the module.
* refactor: better names in concretize functions
Clarify the names of variables in visitor type functions.
* refactor: ensure findType returns a type
Adds an additional check to findType that ensures the retrieved binder
is in fact a type and not another object. This is necessary for certain
contexts like type concretization since modules may also be designated
by symbols that refer to types.
* fix: ensure nested polymorphic types are emitted
This commit fixes an issue whereby nested polymorphic types would not be
emitted by the compiler, even though their member functions were
emitted.
In order to support this, we need to update a couple of functions to
take the global environment (to find nested types, which live in
modules) in addition to the top level type environment. Additionally, we
had to update scoring to account for nested names.
fixes#1293
* test: add tests for nested polymorphic types
Adds regression tests to ensure nested polymorphic types are concretized
and emitted correctly.
* refactor: refactor concretize module

hopefully easier to change. I've also modified some monadic code in the

* refactor: better names in concretize functions
Clarify the names of variables in visitor type functions.
Previously, there was an edge case whereby types that depended on other
types that were not scored yet and functions that in turn depended on
these types could be assigned the same score. When this happened, we'd
sometimes incorrectly emit functions before the struct types they
depended on.
Since functions are always at the bottom of a type hierarchy (they
always depend on their members), there's a simple fix: we just add 1 to
ensure functions are emitted after type declarations in all possible
cases.
