This is very possible... there are various ways to do it, but
that's what metaprogramming is about.  Regardless of how you
get there you end up with something about as elegant as you
could ask for (obj:method(), obj.attribute), but you have to
'do it yourself' (though a simple implementation is already
very simple).  So I can't see a 'blessed' way of doing
this making it to the core, but I assume it's already well-covered
by projects such as LuaCheia (and definitely amply covered by
the Wiki code).
