On balance, I think this is my favourite proposal so far.  Perhaps my
only niggle is I'm used to parentheses around an expression resulting
in that expression returning only one value, though I assume \ x,y
(x*x, y*y) will return two. Still, for me personally the trade-offs
with this solution are the easiest to stomach of the proposals I've
seen so far. I particularly like that the syntax works well with
functions containing statements as well as those which just return
expressions.

I don't suppose you've looked at implementing this patch for LuaJIT 2?
