The way other Lisp-like languages like Clojure work is by returning
either nil (if no match), a string (if the regular expression matched
the string and didn't have any capture group), or a vector where the
first element is the entire match and the rest of elements are the group
matches.

I think it's a nice API, specially because you can use destructuring on
the return value to discern the cases.
