   * I found the C- language at http://marvin.cs.uidaho.edu/Teaching/CS445/ and thought it would be a really
   * good test case since it is not at all a trivial language, but it also lacks the complexity of e.g. a full
   * C++ parser, which is not even a context free grammar, and does not require indentation based parsing like
   * Python.
