Thoughts?
I have various enhancement requests or suggestions on
zip/lockstep in Bugzilla, I suggest you to take a look at them.
I prefer the "shortest", because it's used in various languages,
and it works well when one given range is finite and the other is
infinite:
zip([10, 20, 7, 3), [1, -1].cycle)
I think the zip() name is the most common in languages. Adding a
third is not easy. And I like the zip name.
I have suggested to deprecate lockstep and keep zip only:

zip(A, B) is currently not nothrow, and this is bad. I suggest to
give it the kind of iteration (shortest/longest/etc) as template
argument. So the shortest (that I think should be the default, as
now), can be specialized to be nothrow:

https://d.puremagic.com/issues/show_bug.cgi?id=6034
https://d.puremagic.com/issues/show_bug.cgi?id=8715
In the ER 8715 I have suggested to add to zip _optionally_ a
mapping function, so it becomes like zipWith of Haskell:
static struct Vec { int x, y; }
auto r2 = zip!Vec([1,2,3], [10,20,30]);
This is very handy and it's more efficient and shorter than a
zip+map.
