Should we kill ipairs, as attempted in one of the 5.2 releases? What about _ENV? That sounds straightforward too. Ah, yes, goto will be a walk in the park as well.

It's not so much about saving mythical users, but about making it
easier to do the right thing. With module it's easy to get things
wrong by even a seasoned campaigner as the deeper semantics are
non-trivial and not obvious. When replaced by the arduous few lines
required in 5.2 the semantics are clear to anybody with a basic grasp
of Lua constructs.
