For issues such as these, the Lua reference manual is your friend: 
<http://www.lua.org/manual/> (Pipmak still uses Lua 5.0, not 5.1; this is 
supposed to change at Pimak 0.3.0).  In my opinion, Lua is one of the weirder 
languages--perhaps because it is not a general purpose language?--so keep it 
on hand whenever using Lua ;).  (I still prefer it as a game engine's 
interface, though.)
