One of the unwritten rules of Ruby Quiz is to do whatever seems
appropriate with the interface, given the real interface.

You'll notice, for example, that a Regexp returns the offset from =~, a
boolean from === (despite the documentation's claims to the contrary),
and a MatchData object from #match.
The alias_method part of the interface simplifies this aspect of the
interface to DictionaryMatcher, although it defintiely makes more sense
to invent a MatchData object of some sort that can tell you what the
matched word was, and use that as the return value to match.
