There is an old ES4 proposal for typed vectors, but it wasn't updated
since almost three years. Also see LPP-6709.

(I think that most runtimes create typed arrays for you, under the covers, as an optimization. We know for instance, that even as2 watched the keys of array and used a different implementation if all the keys were integers in a small range [we know this because there were bugs in their implementation at first].)
