Question about Lua performance (locals vs globals)

["Chris Camfield" <chris-camfield@...>]

Hi all,

I understand from previous threads that using globals is more expensive  
than locals.  What I'd like to ask is - is this based simply on the number  
of table lookups, or is there anything beyond that?  I assume that the  
cost of any table lookup is equal, including referencing "self".  Is that  
right?

Thanks in advance,	
	Chris
