I suggest adding a way to provide a custom precedence for the token regexs. I'm currently stuck because as far as I can tell, there isn't one.
Currently, it always sorts by the first line number of the function, which is nice if you're defining the functions manually, but a huge pain if you're defining the rules programmatically. Since foo.__code__.co_firstlineno is a readonly attribute, there is no way at all to specify the regex precedence.
Providing explicit methods rather than relying on function internals might also make the code more portable.
