How about changing the label syntax to "name::" where :: is a new lexical
There's an amusing syntactic difference in the functional programming
world, where ML uses :: for linked list construction and : for type
annotations, but Haskell is the other way around. So C++ uses : for labels
and :: for namespacing, and with this suggestion Lua would use :: for
labels and : for methods (with a vague handwavy connection to namespaces,
please ignore the man behind the curtain).
