Can we just do this instead for seebase?

function package.seebase(mod)
   local env = {}
   setmetatable(env,
        { __index = setmetatable(mod, {__index = lua_libs}),
          __newindex = mod })
    return env
end

More indirection, but no function call. Since we're already copying
package.loaded._G can we just lazily cache those in the mod table too?

-------------------------------

Other people have been complaining about the module discussion on the
list recently, but I think it has been productive too.

I think we may be close to a solution that will have broad approval.
