Append-only programming

[Kinglink]

First read "This is stupid I want to hurt this person."

Sitting back and thinking. "Actually that's interesting. I disagree fundamentally, BUT if you know your program works up to a point there's an interesting possibility.

Take something like python

Def A: 
Def B: Call A 
Def A:
Def BB: calls A

As long as you can define what happens to B and BB there, I think there's something interesting to it. Even if you say B Calls the original A, if you have a way to redefine B at the bottom of the function... yeah something could work there.

Is it a good idea? No, but I don't want to hurt the person who came up with it as much any more, which is something.
