Yeah, switch(true) has always felt like an ugly hack to me. If I ever do write
up my idea I'll cover this in the RFC, but the main problem is that you have to
repeat the "$foo ===" part in every case, which means a reader can't assume all
the cases are of the same form, and in many situations you're better off just
using elseifs.
A switch(true) makes more sense if you have a bunch of basically unrelated
conditions with the same outcome, at which point a bunch of case labels is
possibly easier to maintain than a big chain of boolean ors.
