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
module(...)
require("newstrict")
where newstrict starts:
local GLOBAL_TABLE = getfenv(2)
local mt = getmetatable(GLOBAL_TABLE)
if mt == nil then
mt = {}
setmetatable(GLOBAL_TABLE, mt)
end
Now I wonder if you could get newstrict to replace module or setfenv with a version that does this for you.
Any insight?
Cheers,
Geoff
