Augh! I just realized I screwed up the names. Joy, while an
excellent and cool language (it's a functional Forth, more
or less), is fully and totally 100% Turing-complete.

The language that I was /actually/ talking about is Charity,
which is a categorical programming language invented at the
University of Calgary:

Sigh -- my apologies for any confusion I've caused. :(
