Sorry if I've offended you, but I'm not *demanding* anything. I'm also
not talking about a hypothetical non-lua language, I'm trying to
understand a justification for something that I see as counter intuitive
within the language am I trying to use.

I would have thought if you were calling a function you would want to
know what it does!

The same argument can be used for what I am trying to do, only I *have*
to use temporary variables. What I was trying to do is:
-- Do stuff
As it is, I have to do:
local x,y = Position()
This is hardly a hardship, but as I keep saying it *seems* counter
Oh, and just to throw a bit of petrol on the fire, if I saw code like
"a, i = f(a+1,i), f(i,a)" I wouldn't have a clue what it was supposed
(It's so hard to leave interesting discussions)
