Well, there are many things that we deliberately do not match right
now and for which that's a good thing:

  label:
  public:
  void declaration_only(...);
  int global_variable;

At some point I was wondering whether it would be better to just
declare a non-match for '.*;' and '^[A-Za-z_][A-Za-z_0-9]+:', and
otherwise match all '^[A-Za-z].*\(' but I may be missing something.
