This now works (just checked the code in)

def fact(i):
 if i < 1:
  return 1
 else:
  return i * fact(i - 1)

print fact(10)

We can recurse to any depth we want (until we hit the 4GB memory limit)- and
the only problem we run into is the integers start overflowing (as I'm
mapping to C data types). Compare this to CPython where I hit a recursion
depth of around 989.

In Smoke, I was able to recurse till somewhere around a million stack frames
deep before I got bored :)
