AFAICT, matching and conversion are totally separate concepts. Despite
some conversions having a relationship with some matchings, there are
times when you want a match filter without a conversion, and vice
versa. And there are times when you don't want to stop to create a new
converter just to make a matching assertion.
If we consider conversion-marker-in the pattern a must-have (I don't
think it is TBH, because we already have it via custom route
predicates), whatever solution we come up with should take into account
the case of someone just wanting to do an unanticipated matching
(probably via a regex) without stopping to create a converter/matcher
utility.
