alt Hacker News break 'label value;
Very often if you think harder you realise you didn't want this, you should write say, a function (from which you can return) or actually you didn't want to break early at all. Not always, but often. If you write more "break 'label value" than just break then you are almost certainly Doing It Wrong™.
Not having put it into practice yet, there is a pattern I use regularly which I plan to replace with the labeled one: I set a flag at the top of the loop I have an inner loop. The inner loop can set this flag. Directly past the inner loop, I check for the flag, then break. I am pretty sure this is exactly what the labeled break is for.
