I am interested in being able to condense the If/Else statement in this sub into a single line which accepts and chomps only digits and calls itself if it gets anything else. Any help?
TIA
jg
sub input {
    my $arrayref=shift;
    print "\nSo far you've guessed @$arrayref."
          if $arrayref;
    print "\nWhat is your guess?\n";
    chomp (my $in=<STDIN>);
    if ($in=~ /\d/) {
            $in;
        } else {
            print "$in was not a number!";
            input();
        }
}
