So what do you think it should be, a struct?
That would imply to me that everybody's favorite pastime is making
value copies of regex structures, when in fact nobody does that.

Regex is a class in order to give it reference semantics and provide
encapsulation of some re-usable state.  Maybe it should be a final
class, but my impression is "final class" doesn't really work in D.
