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 ?

i did quite some experiments with it and the 'oo' string calls are
indeed faster

concerning typing, this is true when applied to variables, but on inline
strings it looks kind of weird, compare:

string.format("abc: %s",123)


("abc: %s"):something(123)
