[New-bugs-announce] [issue44731] Simplify implementation of the union type

[Serhiy Storchaka]

New submission from Serhiy Storchaka <storchaka+cpython at gmail.com>:

The proposed PR simplifies implementation of the union type by removing direct support of typing types. It was not necessary because all these types implement __or__ and __ror__ methods.

The only visible difference is that int | TypeVar() etc returns now typing.Union instead of types.Union. But TypeVar() | int already returns typing.Union.
