You can't keep a good concept down ;)

I also worry about the magic-ness of 1 here, as well as the magic-ness of _ENV.

It's a question of how much sugar a person needs, but

in t do x = 10; y = 20 end

seems easier to read than

do local _ENV = t;  x = 10; y = 20 end

But it can always be a macro ;)
