Note that to-integer (or to integer!) isn't always required to return an integer with
division...
>> type? 3 / 2
== decimal!
>> type? 4 / 2
== integer!
>> type? 12 / 4
== integer!
Which also allows us to do the likes of this...
>> x: 5 and 254 / 2
== 2
>> type? x
== integer!
I suspect this has speed advantages too, though I've not done any tests.
