I wish Lua had "env stacks"[1]

It does: use "local _ENV=" instead of setenv:

    local _ENV={print=print}
    print "normal stuff"
    do
    	local _ENV= {print=function()
    		print "not normal"
    	end}
    	print()
    end
    print "normal stuff, again"
_ENV doesn't use a special value in the VM, thus it's a one-way thing. How do I get the _ENV from obfuscated bytecode?
