Ruamoko currently doesn't support `const`, so that's not relevant, but
recognizing `char *` (via a hack to work around what looks like a bug
with type aliasing) allows strings to be handled without having to use a
custom parser. Things are still a little clunky for custom parsers, but
this seems to be a good start.
It worked as a proof of concept, but as the code itself needs to be a
bit smarter, it would be a lot smarter to break up that code to make it
easier to work on the individual parts.
