run time code generation in python

[Carlo v. Dango]

Hello there. I have found a need to runtime generate a method and instert 
it into an object instance. The code is a simple forwarding mechanism like

def foo(self, *args, **kwargs):
    self.i.foo(*args, **kwargs)

method.. however, it is only at runtime that I know the name "foo" so I 
cannot gerenate such a method any sooner. I have tried the compile(str) 
method but I haven't succeeded. I've tried using the __getattribute__ but 
there is a problem in that I do not know if __getattribute__ was called due 
to a method call taking place, or due to someone who just wants a reference 
to a method.. (and for other reasons as well :) I need to runtime generate 
the above method.

hope some one has some good pointers to run time code generation in 
python..

many thanks
