Making a 'read-entire-file-into-a-string' function. Reads the whole thing in one chunk (uses fseek/ftell to compute the length), and seems to handle unicode just fine.

Matcher for optionally-signed ints. I think this wraps up the primitive stuff that's common to most/all languages.

More prefix matcher combinators (well, to the extent that's possible without closures), and less ad-hoc testing.

It turns out I can pass function pointers as va_args -- just need to typedef their signatures to make them star-able.

Basic combinators for tokenizing. Unfortunately, I can't use va_args because it can't handle the signatures of function pointers.

Basic string prefix matching functions for tokenization. Based on previous parser-writing experience, I don't think I'll need a general-purpose regexp library.
