Speed up pathlib.Path.glob() by working with strings internally #117586
Description
pathlib.Path.glob() currently generates Path objects for intermediate paths that might never be yielded to the user, which is slow and unnecessary. For example, a pattern like **/*.mp3 is evaluated by creating a Path object for every directory visited.
There are already few tricks employed to avoid instantiation, but it would be better if only real results were converted to path objects.

The documentation doesn't seems to have been updated yet:
3.14.8 Documentation » The Python standard library » File and Directory Access » pathlib — Object-oriented filesystem paths
The above still says that lists of paths are returned.
