A Brainf__k compiler in C++

For fun, I wrote an interpreter for a programming language with a rude name, in C++.

It's available here: https://gist.github.com/kristopherjohnson/e5fc3d19c251dc561f62

There are other C++ interpreters for this language, but most of them look a lot more like C than like C++. My goal was to avoid archaic C-isms like pointers, fixed-size arrays, global variables, and the use of C stdio and UNIX functions, and write something that looks like "modern C++" (which may be an oxymoron).

C++ beginners may prefer to look at the code for a simplified implementation that represents my first pass at the problem. That is available here: https://gist.github.com/kristopherjohnson/55092ba62e82c2166125

A collection of BF example programs is available here: http://esoteric.sange.fi/brainfuck/bf-source/prog/. It pleases me that the ones I've tried all work with my interpreter. The hanoi.bf program is especially impressive.
