Class YieldNodeInContextManagerFunction

A data flow node that represents the value yielded by a callable with a contextlib.contextmanager decorator. We treat this as a normal return, which makes things just work when used in a with statement – technically calling the function directly will give you a contextlib._GeneratorContextManager instance, so it’s a slight workaround solution.

See https://docs.python.org/3/library/contextlib.html#contextlib.contextmanager
