`tempfile.NamedTemporaryFile`'s return type (`_TemporaryFileWrapper`) has any attribute

[DetachHead]

import tempfile

with tempfile.NamedTemporaryFile() as file:
    reveal_type(file) # tempfile._TemporaryFileWrapper[builtins.bytes]
    file.asdfasdf # no error

_TemporaryFileWrapper doesn't extend any, but has a __getattr__() returning Any. This matches the implementation, and would be hard, but not impossible to change: We could look into the actual file object created by the various TemporaryFile functions and copy their attributes over to _TemporaryFileWrapper.

This makes _TemporaryFileWrapper conform to os.PathLike[str].

import os
import tempfile

path: os.PathLike[str] = tempfile.NamedTemporaryFile()
