I propose we just allow (but not require) popFront() to return
ElementType!(R) instead of void?
That way, people who need the performance can check to see the
return type, and use it without front() if needed.
That would be almost perfect. But has drawbacks:
* if element is big and may be not needed in all calls to
popFront (when the user wants to ignore elements), there would be
some overhead;
* it might be impossible to change some ranges which would work
with current design; I'm not aware of such cases, though
* something else?
