Yes.

OK, my real question is: is there a pre-defined iterator adaptor for doing
this, as the generator adaptor doesn't allow for a stop condition?

If there is, I'll use it. If there isn't (and it didn't appear to me that
there was), then I'll have to write my own Policies. Not a biggy, but I don't
want to duplicate effort if I don't have to.
