Yes, it would be hard, and it would radically change the way the language
works. (Python does this. I invite you to go and look at the way it works and
then decide whether you think it's a good idea...)
FWIW, Raffaele Salmaso wrote a very neat object system based on closures where
you used . to invoke methods. Pluses: the syntax change; instance data in
methods was stored as upvalues, not table entries, making them an order of
magnitude faster to access. Minuses: constructing objects was far more
expensive, as you had to construct new closures for all the methods to bind
the self parameter in. If you're interested, he posted his code to the
mailing list; look for December 2004.
(We should really be collecting object systems on the Wiki. There's a fair
number, all with different and useful properties.)
