I did the following:
> print(_G)
table: 00C31B98
> print(_ENV)
table: 00C31B98
> print(_G._G)
table: 00C31B98
> print(_ENV._G)
table: 00C31B98
> print(_ENV._ENV)
nil
> print(_G._ENV)
nil
when I do print(_ENV) doesn't it access the variable _ENV._ENV? but printing _ENV._ENV is nil. So does it mean when I access any other variable aexcept _ENV it is accessed as _ENV.var?
So this means that a running code cannot change its own environment as it could do in Lua 5.1.
