At the moment bogus input will cause problems. We kinda assume things are well-formed, because we're very naive.

If we wanted to be robust we should implement a lexer/parser, and work on tokens. We could then add error-handling, proper test-cases, etc, etc.

• This would make the code bigger.
• It would allow us to support both C and Assembly language output though.

Not a huge priority, but I guess I could take a look at it in the near future.
