Yes, I was aware of that, just that the change in question proved to be 
not-so-innocent :)

While we're on this topic, there's another possibility:
introduce 'continue' for 'while' and 'for' loops and make it invalid in 
'repeat' loops (compile-time error). This would have a benefit of 
keeping backward compatibility.
