Re: OO call vs normal call

["Olivier Delannoy" <olivier.delannoy@...>]

Can anyone give some explanation on why the OO syntax is quicker for string ?
Whether it is the case for any objects/classes (user data or lua based
object)  ?

Are the two syntax handled differently in the lua internals and what
might affect performance of one syntax over the other ?
