Note that this is a two edged sword, in that all those people "toying"
with "with"-like constructs might also be publishing code using them,
meaning that instead of having one clean construct from the core
developers, we'd have to deal with an unknown number of variant idioms
from most anybody.
A small core language doesn't help a lot when you have to know four or
five different ways to build some basic construct because it's not in
the core language.
