- TypeAliasType: lazy value evaluation via closures, __module__,
  __parameters__, __iter__, evaluate_value, check_type_params,
  IMMUTABLETYPE flag, Hashable/AsMapping/Iterable traits
- TypeAliasType constructor: positional-or-keyword arg validation,
  duplicate/unexpected kwarg rejection
- type.__annotations__ setter: distinguish None assignment from deletion
- Annotation scope: name as __annotate__, format as positional-only,
  __conditional_annotations__ uses Cell for both load and store
- Compiler: proper TypeParams/TypeAlias scope with closures,
  find_ann covers match/try-except handlers
- symboltable: deduplicate TypeAlias value scope code
- GenericAlias repr: handle list args, avoid deadlock in repr_arg
  by cloning items before calling repr
- AST types: remove IMMUTABLETYPE (heap types, mutable)
- pymodule macro: preserve existing __module__ getset descriptors
