You've been thinking again, Ron ...

I'd be surprised if they had (see below).

What would you pickle and what not? The reason that a function is stored 
in a module is often because the module contains other supporting code 
that it needs. Generally the elements of a module should have a 
higher-than-random degree of interdependence.

This would be quite a feat of introspection if you could do it.

As another respondent suggested the savings of this technique would 
likely not be a reasonable return on  the development and support effort.
