I'm not concerned by the vote.

"break" should be consistant with "continue"
so break labels could only be "like Java".

if confused with "goto", what are labels then ?

the case is very well shown by someone in the list, can't find the post 
back, as:

etiquette: while (...) {
     ...
     break etiquette; // breaks loop, next after the }
     ...
     continue etiquette; // continues loop, next after the {
     ...
     goto etiquette; // breaks and restarts loop
     ...
}

I can see what the 3 do with respect to any vote conclusion here.

Mixing "goto" with "break" and "continue" could bring confusion.
Not necessarly if established that goto will break any loop up to the 
one where the target is.

Assuming labels can also be applied to non "loop" constructs, then goto 
should break all loops up to the loop labeled by etiquette or containing 
etiquette on its direct level.

Finally, I see goto as a nightmare, here.

Last troll's note:
goto has 2 "O" as Object Oriented
