[HDGEM] Tail call optimization (TCO)

Some compilers and interpreters will do what's called tail call optimization (TCO), where it can optimize some recursive functions to avoid building up a tall call stack. Python and Java decidedly do not use TCO. Some Ruby implementations do, but most don't. Some C implementations do, and the JavaScript spec recently allowed TCO. Scheme is one of the few languages that guarantee TCO in all implementations. In general, best not to assume your compiler/interpreter will do this work for you.
