Well, yes, but isn't the existance such module would be a "hack
against the Lua 5.2 language"? Almost the same as if one would create
a module which would allow people to bypass the __metatable
protection.

Note that I'm not advocating the removal of get/setfenv, but merely
discussing the "what if" Lua 5.2 final *is* released without them.
