Returning a cursor sounds like a reasonable idea, and it even seems
like it would not be all that hard to do, as a sort of filter over the
basic iteration operation.

I was thinking of suggesting passing the match operation a predicate to be 
called on each potential match, to decide whether it should be returned. 
But I think I like the cursor-based approach better, as it's somewhat more 
general.
