I took a look at these issues, but they seem tricky to implement in
druntime because they depend on phobos features. So probably
constructing an AA from zip() should be in phobos; the current AA
methods should be already be good enough for implementing this.

For iterating AA's as key/value pairs, though, I'll have to think about
how to do it in a nice way. Internally, there's already a Range struct
that iterates by Slot (which amounts to the same thing as iterating by
pairs), so it's just a matter of exposing this in the right way to the
phobos code that will implement by-pair iteration.
