Thanks, Steve!

How does strict work with modules?

As far as I can tell, strict.lua (pl's and lua's) both change the metatable of _G.  But inside a module the global environment is _M.  How is _M affected by what you did to _G?
Don't you need to do something like the following?

local require = require

where newstrict starts:

local GLOBAL_TABLE = getfenv(2)
local mt = getmetatable(GLOBAL_TABLE)
if mt == nil then
  mt = {}
  setmetatable(GLOBAL_TABLE, mt)

Now I wonder if you could get newstrict to replace module or setfenv with a version that does this for you.

Any insight?
