There is the general Python problem, that a running frame does
not exactly know about its function object. There is only a name
and a filename available in the code object, and the code object
is the only thing a frame knows about.
I think to propose a PEP about this.

In most cases Stackless could do that.
Given a reliable way to deduce the module/function from a frame
(see above), it would be possible to edit the function, create
a new code object, and create a new frame.
