Not quite.

Let's say I have function 'F':

def add(a, b): return a + b

And a base class of 'C' which does all the __init__ stuff or
whatever's needed,
the function 'add' should return a new class __init__'d with a and b,
but 'add'
should be the __call__ of that instance.

Hope that makes sense, and TY for your post,

Jon.
