The recommended way of writing modules is the trivial way: a module should
return a table with its data and functions. It'd be nice if it also did
not pollute the global environment. In Lua, this is done trivially with:
function M.f() ... end
This way works fine for both 5.1 and 5.2
There is no need for a module function and no need for syntax either.
No one needs to know about _ENV for that only for complicated things
like avoiding writing "M." (probably not a good idea as it serves as
documentation of what is exported).
All my C modules follow this (but do create a global as well). Changing
them to 5.2 is really easy, even removing the creation of the global.
I do not see any big deal here.
