This isn't what I was suggesting - I meant something like this:
class instancemethod: def __init__(self, wrapped): self.wrapped = wrapped def __get__(self, obj, objtype): if obj is None: return self.wrapped else: return MethodType(self.wrapped, obj)
this wouldn't be useful for functions, but would give other callables the same functionality as functions, automatically creating the bound method object, e.g.:
class D: def __init__(self, obj, *args): ...
class C: foo = instancemethod(D)
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.
