It could become unnecessary if you're working with value objects. If you had
ordinary numbers, you'd have to coerce them to u32 and then multiply:
var a = 0x7fffffff, b = 0x7fefefef; // both doubles
var result = int32(a) * int32(b); // int32
But value objects are still uncertain and at the very least much farther off
into the future -- post-ES6. Engines could implement and ship Math.imul in very
short order.
