Nothing too deep. It just strikes me that functions are objects too, and there are
variations like closures and generators and bound methods etc, yet the process of
creating these things is not exposed for customization in a unified way. I'm not sure
what would be in the dct if cls,name,bases,dct were passed to a meta-something on
completion of the function definition, analogous to metaclass at the completion of
class definition, but I assume the code object would be there and tinkerable at
the __new__ stage in a way that might not be possible later. E.g., being able
to add pre-bound local variables to a function might be interesting (like default
arg values, but not in the arg list).

Maybe with module new and some clever hacks a user function class could be worked up
for concept testing. Lots of handwaving here ;-)
