A C<goto LABEL> is considered a bad practice by a number of people, as it can lead to hard-to-understand and brittle spaghetti code.

Who cares what management thinks? Perl's goto LABEL is an awesome tool when one wants loop-like flow control outside of loops. It's the easy way to implement interactive shell scripts: 


INPUT: print 'number> ';
chomp(my $input = <STDIN>);

if ($input and $input =~ /[0-9]+/) {
  print $input, "\n"
}
else {
  goto INPUT
}
