No you're definitely moving into sceme country... :)
What is the above supposed to mean? Or, rather, what
would you like x to be? 10? What is the return value
of a loop -- the return value of the last
expression/statement in the loop? Or should we perhaps
use a "return" statement in loops as well? Or make
"return" statements obsolete in functions?
This might be a good ideas in some languages, but in
a (predominantly) imperative language, it seems...
well... strange to me.

The problem is that you usually maintain other people's
What you are proposing is in essence a completely
new/different language; scheme with "imperative
syntax" so to speak. If you make it I will most
certainly play with it, but warping Lua to such a
degree seems excessive (and improbable).
