From a posting of mine I made in 1998 in one of the Perl groups: 
And you can do that in Perl as well:

my $n = int (($count + 7) / 8);

goto (qw !LABEL0 LABEL1 LABEL2 LABEL3
          LABEL4 LABEL5 LABEL6 LABEL7!) [$count % 8];

{
    LABEL0:  print "0\n";
    LABEL7:  print "7\n";
    LABEL6:  print "6\n";
    LABEL5:  print "5\n";
    LABEL4:  print "4\n";
    LABEL3:  print "3\n";
    LABEL2:  print "2\n";
    LABEL1:  print "1\n";
    redo if -- $n > 0;
}

It's certainly legal to jump into a bare block, and bare blocks are looping constructs as well.
