This has been discussed from time to time already, and it's not
immediately clear that allowing this is desirable.  See:

http://lua-users.org/lists/lua-l/2008-12/msg00164.html

In any event, even if Lua 5.2 were to adopt "x":y() as valid syntax,
my original statement that this proposal "wouldn't break any existing
code" still stands.  (I admit that literals as labels might be less
desirable in such a world, however.)
