This makes labels somewhat less general, but maybe C should be
handled separately, anyway. For example, maybe you can only use C
if you've asked to "use continuations;".

List of pairs and left-to-right writing:

Well, of course you run the danger of making it hard for people to
recognize labels which are otherwise common across many languages, but
here's a few ways you could do labels if you need

Hello all,
I have been going over the Synopsis, and I cannot find block labels
mentioned anywhere. I was under the impression that if it is not
mentioned, then it can be assumed to be the same as perl5. However, I
wonder if this is the case with labels given that "everybody wants the

Using goto LABEL? No. ;)
Would be nice if Perl warned one about multiple labels of the same
name in the same call stack, though.

Hmm is this such a good thing?
my $a = 0;
GORK: while( 1 ) {
print "Rin ";
GORK: if ( 1 ) {
print "Tin ";
goto GORK if $b ^= 1;
print "\n";
next GORK;
}
}

What if we could use C to exit valued iterators? Currently we cannot
because labels can not appear within statements, only on their own.
