I agree. Like you I couldn't really care about a 'goto', I'd probably never
use it. But labeled breaks would really add something to the language. The
current break counters aren't very user friendly if you ask me.
I'm very much in favor of:
LABEL: while (cond)
{
...
break LABEL;
...
}
I've seen it being mentioned that the 'LABEL' would be appended to the while
loop, something like this:
while (cond)
{
...
break LABEL;
...
}
LABEL:
But I think that's absolutely hideous and looks like a 'goto' (which is most
likely why people began talking about adding 'goto' in the first place). If
it were up to me (and it's not), 'goto' will not be implemented in any form
and the break keyword can refer to numbers and labels and in case of the
latter, these would be PREpended to the loop construct.

I'm completely indifferent about goto (in any form), but *PLEASE* can we
have labelled break/continue -- something like:
LABEL: while (cond):
...
break LABEL;
...
endwhile;
or
while LABEL (cond):
...
break LABEL;
...
endwhile;
or
while (cond) LABEL:
...
break LABEL;
...
endwhile;
I can't tell you the number of times I've broken my own code by adding or
removing an inner loop and failing to notice that a break/continue count
needs incrementing/decrementing. Labelled breaks are a relatively simple
addition to the syntax that would improve the programming experience out of
all proportion. Yes it's complete syntactic sugar -- it doesn't do anything
you can't currently do, just does it in a much more friendly way -- but
incredibly helpful sugar ;)
Cheers!
Mike
