Source Code Leaks

Any information on source code leaks? I'd love to get my hands on the source code for some older xbox games. Specifically Time Splitters 3. Its funny how games get leaked all the time but source code is always shut up tight.

There's also the matter of creating a function
Cant create a simple function? That is why C/C++ sucks. Use real language, like Lisp, cause Lisp has no problems creating functions and you dont even have to write annoying types.
