[ANN] Lua 5.2.0 (final) now available

The Lua developers are generally not very fond of endorsing a single "right way" to do things. But basically, it's something like:

    -- localize all the stuff you need
    local _ENV = {}
    -- module code
    return _ENV

So really not that much code to add yourself.

An easy way is to just define your functions in a table, and at the end of the file to be required, return the table. This was the pattern used in Lua before 5.1. The source for Luacov provides a clear example:

There was a more detailed summary at http://www.lua.org/work/doc/#changes but it looks like it's been taken down. There's the Google cache: http://tinyurl.com/832f273
