Actually, Ada can do this too, I'm pretty sure, even without using its OO 
features.

Plus, heck, in Erlang you can make that change without stopping the program 
and without losing any data.

If you look at the source for Wings3D, you can see where there are pieces of 
code that basically say "hey, there's a new version of the code, load it and 
run it *without* closing my window, saving the shape i'm working on, etc." 
I.e., the developer could find a bug while working, fix the bug, and keep 
working except with the new code running.

OO isn't going to give you *that*.
