digitalmars.D - Turn .opApply into ranges

I wondered if I can turn struct that defines opApply into ranges.

And it turns out to be surprisingly easy:

Maybe we can phase out opApply support in foreach? ;)

BTW, is there a way to get the "element type" from .opApply?

This "conversion" relies on fibers which need heavy runtime support. So no, opApply still has it's place.
