[Issue 18807] RefRange behaves very differently for Input Ranges and Forward Ranges

Indeed, and both are worth fixing.

So I think it makes sense to keep these 2 issues:

issue 14619 should fix compiler's foreach behavior (calling opSlice
unnecessarily)

this issue should fix RefRange in phobos, to avoid defining opSlice().

There are 2 issues here. One is the same from 14619 -- the compiler is assuming
opSlice  on a valid range is a no-op.

The second issue is that for some reason opSlice is defined in RefRange iff
save is defined. That makes no sense.

Fixing either of these issues will fix the problem I think.

It's related -- but that issue is about "foreach" behavior, and this issue is
about RefRange behavior, which probably should not define opSlice (as mentioned
in passing in issue 14619).

Possibly a duplicate of issue 14619.
