I'm not sure how regexes handle these things internally (and, yes, it 
*would* be nice to have one-sided ranges natively), but for things like 
case equality I've found it pretty easy to make quick-and-dirty classes 
like GreaterThan  [e.g.  when GreaterThan.new(6)].

Of course, I abandoned this approach for something less ugly... ;-)
