I don't know about others, but I don't understand exactly how
your three versions differ, and exactly how you extrapolate from
direct recursion to mutual recursion. I would need access to the
source code (both .m and .c, if the compiler generated .c is hand
modified), and I would strongly prefer that the exemplar program
itself be mutually recursive.
