yeah.. I am not quite sure myself about it. But skipping on the div
emulation seems like a good idea in general. But it's also not common
enough to actually care all that much about it.

You handle 1/n but not 1%n? TBH, the 1/n code isn't 100% obvious to
me... 1/n = |n|-1 > 0 ? i forget how SLCT works, but I can't
