No, there doesn't. The table lookup (__index) is neither local nor
global, it's a table lookup. And the implicit metatable access doesn't
have ANY overhead at all -- the metatable is just a field on the
object's internal structure. Obviously calling getmetatable() yourself
has the overhead of looking up the getmetatable() function and the
function call itself.
