Francesco,
thanks a lot for your efforts! I will try it out.

Absence of the "continue" statement is very high on my Lua complaint
list. That said, you can emulate it using break inside repeat ...
until true construct like this:

for i=0,9 do
 repeat
  if i>=3 and i<=7 then break end  --exclude i= 3,4,5,6,7
  print(i)
 until true
end

According to Roberto http://lua-users.org/lists/lua-l/2006-12/msg00441.html
this method generates optimal opcodes for "continue".
Unfortunately, you cannot have "break" and "continue" behavior withing
the same repeat...until block.

Hope it helps,
