One good thing for safety and CTFE is allow multiple return

auto ref front()

return (a.front, b.front);

Mir libs will use pointers for now. This is one of reasons why
`zip` is slow.
The new feature also significantly extends std.range and
std.algorithm functionality.

I am not good in DIPs and hope someone is interested in this
feature too
Do tuples work for this?
No, tuples stores either value or pointer. If it stores pointer
then it is not safe and it is not CTFE.
