1f7dfb277e bpo-42233: Correctly repr GenericAlias when used with typing module (GH-23081) 
Noticed by @serhiy-storchaka in the bpo.  `typing`'s types were not showing the parameterized generic. 
Eg. previously:
```python
>>> typing.Union[dict[str, float], list[int]]
'typing.Union[dict, list]'
```
Now:
```python
>>> typing.Union[dict[str, float], list[int]]
'typing.Union[dict[str, float], list[int]]'
```

4f3c25043d bpo-41923: PEP 613: Add TypeAlias to typing module (#22532) 
This special marker annotation is intended to help in distinguishing
proper PEP 484-compliant type aliases from regular top-level variable
assignments.

044a1048ca bpo-38605: Make 'from __future__ import annotations' the default (GH-20434) 
The hard part was making all the tests pass; there are some subtle issues here, because apparently the future import wasn't tested very thoroughly in previous Python versions.

For example, `inspect.signature()` returned type objects normally (except for forward references), but strings with the future import. We changed it to try and return type objects by calling `typing.get_type_hints()`, but fall back on returning strings if that function fails (which it may do if there are future references in the annotations that require passing in a specific namespace to resolve).

653f420b53 bpo-41341: Recursive evaluation of ForwardRef in get_type_hints (#21553) 
The issue raised by recursive evaluation is infinite recursion with
recursive types. In that case, only the first recursive ForwardRef is
evaluated.
