[New-bugs-announce] [issue30948] Docs for __subclasses__(): Add hint that Python imports are lazy

[Thomas Guettler]

New submission from Thomas Guettler:

AFAIK cls.__subclasses__() only returns the classes which the interpreter has already loaded.

This means there can be more subclasses in modules where not imported by the current interpreter up to now.

https://docs.python.org/3.7/library/stdtypes.html?highlight=subclasses#class.__subclasses__

I think it would be nice to add a hint to the docs that python imports are lazy.

What do you think?
