I checked up on the phobos implementation and found that arrays 
are mutated when iterated over as ranges, which didn't rest well 
with me. Nor did the idea of importing some module having such a 
significant side-effect as whether some type can act as a range 
or not. So I ended up making a sort of factory that turns 
arbitrary objects into ranges, including arrays. Seems to work 
pretty well.
