Thank you for your kind words. :-)

"Abuse", you mean. :-) Note how many template classes the
compiler instantiates. And how many std::strings are
instantiated at run-time (and never released). Catching
std:ut_of_range to stop recursion is pretty damn evil
too - I didn't even know I had it in me. I almost hope the
OP submits this to his instructor.
