in thread removing the goto

Erm... wasn't the goto label placed below the foreach in the OP, and a goto dinn' advance the iterator?

--shmem 

_($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}

    The point of redo is that it does not advance the iterator.
    The redo command restarts the loop block without evaluating the conditional again. 
    my $redid = 0;
my @list = (1..5);
xyz : for (@list) {
    print;
    redo if $_ == 3 && ! $redid++;
}
# Output: 123345

      Thanks... now I got it *blush* - the difference between redo and next.
      Shame on me.

      --shmem 

      _($_=" "x(1<<5)."?\n".q·/)Oo.  G°\        /
                              /\_¯/(q    /
----------------------------  \__(m.====·.(_("always off the crowd"))."·
");sub _{s./.($e="'Itrs `mnsgdq Gdbj O`qkdq")=~y/"-y/#-z/;$e.e && print}
