More than just allowing Zip to be used in a "foreach ref", the real issue is
the code compiling at all:

Issue 11934 - Allow `ref` in `foreach` over range iff `front` returns by `ref`

Issue 11934 - Allow `ref` in `foreach` over range iff `front` returns by `ref`

Issue 4707 - auto ref for foreach loops

As for this specific issue, I don't really see any way to fix Zip, short of
putting lockstep's opApply code into Zip.

As a matter of fact, why don't we just do that? Performance? I seem to remember
opApply base foreach is slow (creates a delegate)?
