* Fix class-scope inline comprehensions when nested scopes reference `__class__` and friends In `inline_comprehension()`, when `__class__` / `__classdict__` / `__conditional_annotations__` appears as `FREE` in a comprehension's symbol table because a nested scope captured it (e.g. nested lambdas), this name is still discarded from `comp_free` unconditionally. This prevents `drop_class_free()` from seeing it, so the appropriate `ste_needs_(...)` flag is never set on the enclosing class. That leads to `codegen_make_closure()` throwing `SystemError` when it couldn't find `__class__` / `__classdict__` / `__conditional_annotations__` in the class's cellvars. From now on we just discard from `comp_free` when no child scope (e.g. a lambda) still needs the name as `FREE`. When a child scope does need it, keep it in `comp_free` so `drop_class_free()` can set the appropriate flag and the class creates the implicit cell. * Fix tests * Fix typo * Fix formatting * Add test checking validity of `__class__` returned * Prefer 'used' to 'deferred'
