Translations:User:Psychoslave//Lua reference manual translation stub/2470/en

The following functions have been modified:
 * [$url0 setfenv]
 * [$url1 getfenv]: May not be available, depending on the configuration. If available, attempts to access parent environments will fail.
 * [$url2 getmetatable]: Works on tables only to prevent unauthorized access to parent environments.
 * [$url3 tostring]: Pointer addresses of tables and functions are not provided. This is to make memory corruption vulnerabilities more difficult to exploit.
 * [$url4 pairs]
 * [$url5 ipairs]: Support for the __pairs and __ipairs metamethods (added in Lua 5.2) has been added.
 * [$url6 pcall]
 * [$url7 xpcall]: Certain internal errors cannot be intercepted.
 * [$url8 require]: Can fetch certain built-in modules distributed with Scribunto, as well as modules present in the Module namespace of the wiki. To fetch wiki modules, use the full page name including the namespace. Cannot otherwise access the local filesystem.
