[issue21205] Add a name to Python generators

[STINNER Victor]

STINNER Victor added the comment:

gen_qualname.patch: add a new "__qualname__" attribute to generators and change how the name is set: use the name of the function, instead of using the name of the code.

Incompatible changes of this patch:

- repr(generator) now shows the qualified name instead of the name
- generator name comes from the function name which may be different

If the function has a name different than the code (if the function name was changed, for example by @functools.wraps), the generator now gets the name from the function, no more from the code object. IMO it's the expected behaviour, and it's more useful.

I'm writing on email to python-dev to discuss these changes.
