Python Tail Call Optimization Decorator

Tail recursion optimization, not all calls. So no continuations, etc.

And it's probably slow as hell.

And I'll knife you if I see you using Python like this.

See also an alternative implementation in the LTU discussion http://lambda-the-ultimate.org/node/1331#comment-15165.

Also, for those who missed it, Guy Steele's older post about why tail calls are important: http://projectfortress.sun.com/Projects/Community/blog/Objec...

Oh my -- "optimization" is a very poor choice of word here!

Tail call optimization primarily optimizes memory, not time. It will reduce time costs, too(assuming calls are more expensive than jumps, which would probably be true in any architecture), but the memory used is the main issue.

Crash avoidance?
