For the case of the interactive prompt, if preserving
the source code is somehow desirable (which I doubt),
it should be the job of the development environment
to offer saving interactively-defined methods.
Such IDE support is necessary even if __source__ was
available, since users probably would not want to write
open("demo.py").write(myfunc.__source__ + "\n" + myclass.__source)

I think it is the other way 'round. If this is *only* for
interactive mode, than you should *first* change the interactive
environments. If you then find you absolutely need this feature
to implement the IDEs correctly, I'd like to hear the (new)
rationale for the change.
