The key point is that I think think should be the job of the parser and the functionality provided at the interactive prompt w/o the user having to write 'dyndef' or store the code of exec's or request from himself to use specific commands to create functions. It should be transparent built into python.

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)

OTOH, programming python is easy and fun and I think the proposed feature will make it even more fun and it aims in increasing the number of people who program python for their every day tasks. It'd be interesting to hear if the developers of IDLE/ipython/etc could use this.

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.
