g++ and tail recursion

We have been studying tail recursion in my computer class. The prof
told us that some compilers will turn a tail recursion into an
iteration thus allowing many, many function calls to the recursion. I
have proved to myself that the two flavors of VC++ I have will do this
but I cannot get the GNU G++ compiler to do so. It is run in unix on
a sun sparc and is version 3.3.2. It's threading is POSIX. Is there
a switch which will compile a tail recursion on g++ as an iteration?

Is it feasable, and/or desirable to have Python optimize tail-recursive calls, similar to Scheme and gcc -O2? i.e. effectively compile this: def foo(n): return foo(n-1) into this: def foo(n): goto foo(n-1)

This is fun :) {Note: I take no responsibilty for anyone who uses this in production code} #!/usr/bin/env python2.4 # This program shows off a python decorator # which implements tail call optimization. It # does this by throwing an exception if it is # it's own grandparent, and catching such # exceptions to recall the stack.

In the following program I am trying to learn how to use functional programming aspects of python, but the following program will crash, claiming that the recursion depth is too great. I am attempting to make a list of polynomial functions such that poly(3) = 1, poly(3) = 3, poly(3) = 9, etc. Could someone point me in the right direction?...
