If I understand this correctly, old 'break' (without labels) would  
became superfluous as it would be mainly a sugar to break a hidden  
'do ... end' around the innermost loop, like:

do :hidden:
 while condition do
   ...
   break :hidden: -- same as 'break'
   ...
 end
end

If that's the case, would 'break' without labels still be supported  
(one more thing to learn, document, etc.)? Or maybe become a  
deprecated feature?
