I'd leave the dispatch table in your module and export a function that uses it:

BEGIN {
package DT; $INC{"DT.pm"} = 1;
use strict;
use warnings;

use Exporter qw/import/;
our @EXPORT_OK = qw{ dispatcher };

my $typecolors = {
    1   =>  \&release,
    2   =>  \&event,
    3   =>  \&gossip,
    4   =>  \&props,
    5   =>  \&diss,
    6   =>  \&other,
};

sub dispatcher {
    my ( $verb, @args ) = @_;
    $typecolors->{$verb}->( @args )
}

sub release { print "release\n" }
sub event { print "event\n" }
sub gossip { print "gossip\n" }
sub props { print "props\n" }
sub diss { print "diss\n" }
sub other { print "other\n" }
}

package main;
use strict;
use warnings;
use DT qw/dispatcher/;

dispatcher( 2 ); # prints "event\n"

Note that I've written this all in one file. If you're doing this properly, you don't need the BEGIN block that wraps DT, nor $INC{"DT.pm"} = 1.
