Why would you write something like that knowing that f(a) could possibly
return multiple values?  If you want predictable behaviour then do
a = f(a)
i = i + 1

I'll take you're word for it.  

I'm bowing out of this discussion now, I'm still not convinced, but I
feel like I'm fighting a losing battle.  I'll just write it off as
another wierd "lua-ism" to warn the rest of my team about. :)
