--- Comment #2 from Alex Goltman <alex.goltman at gmail.com> ---
If it fails to implicitly copy to a non-const (e.g.  a struct with a pointer
inside) then so be it - but why not make it try at least? as in:

Unqual!(typeof(range)) _r = range;

It seems weird that foreach which intentionally copies the range to avoid
modifying it will fail because a range is an unmodifiable const.
