One good thing for safety and CTFE is allow multiple return
value. In combination with `auto ref` it is _very_ powerful:
----
auto ref front()
{
// Returns 2 values, each value is returned by reference if
possible
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
