$(D Zip) offers the lowest range facilities of all components, e.g. it Params:
offers random access iff all ranges offer random access, and also sp = controls what `zip` will do if the _ranges are different lengths
offers mutation and swapping if all ranges offer it. Due to this, $(D ranges = the ranges to zip together
