>
> Iterators over types and their subtypes currently assemble together multiple 
> iterators, one for each type/subtype, and iterate them together.  For cases 
> where there are potentially 100's or 1000's of subtypes, most of which are 
> "empty", this overhead can be reduced by skipping at iterator creation time 
> the empty ones.
