Is there a module, which does this for me?

#!/usr/bin/env perl
use warnings; use strict; use 5.012;

sub aw_parse {
    my( $in, $max ) = @_;
    chomp $in;
    my @array = split ( /\s*,\s*/, $in );
    my %zahlen;
    for ( @array ) {
    if ( /^\s*(\d+)\s*$/ ) {
        $zahlen{$1}++;
    }
    elsif ( /^\s*(\d+)\s*-\s*(\d+)\s*$/ ) { 
        die "'$1-$2' not a valid input $!" if $1 >= $2;
        for ( $1 .. $2 ) {
        $zahlen{$_}++;
        }
    } else {
        die "'$_' not a valid input $!";
    }
    }
    @array = sort { $a <=> $b } keys ( %zahlen );
    if ( defined $max ) {
    for ( @array ) {
        die "Input '0' not allowed $!" if $_ == 0;
        die "Input ($_) greater than $max not allowed $!" if $_ > $max;
    }
    }
    return \@array;
}

my $max = 20;
print "Input (max $max): ";
my $in = <>;
my $out = aw_parse( $in, $max );
say "@$out";
