Right. But if Lua understood that obj[method] was a member function, it 
could push it implicitly always. And that would get rid of the ':' vs 
'.' issue as well. You always use '.' and the runtime decides which 
functions are object methods and which are static. This might require 
some additional syntax at the point of function declaration, but that 
should not be too hard.

Anyway, never satisfied :-)
