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>
  env.print"ok"
end

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