Thanks everyone for the suggestions :)

It will take me a while to fully absorb them, I ll get back with any queries after trying them all out.

Yes, it is not fully equivalent, but you can workaround the limitation
with something like:

local env = _ENV -- or local _ENV = _ENV if you prefer
do <localonly>

However I think <withupvalue> is closer to what Abhijit was looking
for (if he can live without direct access to globals).
