Description: Summary by CodeRabbit New Features Lazy/eager TypeAlias with cached evaluation, improved subscripting, and a GenericAlias iterator. Bug Fixes Avoid deadlocks when repr-ing lists whose elements mutate the list. Clearer error message for inaccessible free variables. Improvements More robust annotation and type-parameter scoping and conditional-annotation handling. Revised annotations/annotate setter behavior. TypeVar/ParamSpec now infer variance by default. Preserve custom module getset descriptors and prevent setting attrs on immutable types.
