You want a method which does absolutely nothing at all but delegate to a
class constructor or callable object (but not a function), with no
docstring and no pre-processing of arguments or post-processing of the
result.
Seems like an awfully small niche for this to be in the stdlib.
But having said that, I might have a use for that too. Except... I would
need a docstring. And pre- and post-processing. Hmmm.
*shrug*
Seems to me that this might be useful in theory, but in practice we
might never use it, preferring this instead:
class C:
def foo(self, *args):
"""Doc string."""
return D(self, *args)
with appropriate pre- and post-processing as needed.
Interesting suggestion though, I may have to play around with it.
