They covered this in a recent thread.

Your best bet (just like in a language that has a 'goto') is 'return'.

Otherwiset you can 'raise' (irritating style that reminds one of VB), or 
you can add a flag to the 'while' conditions and reset it at the 'break' 
point.

Following these style rules...

        simplify 'if' and 'while' test conditions

        don't 'raise' except in an emergency

        shun long functions - don't go over 30 lines or 2 loop statements

...you'l see the best fit is 'return'.
