DL Why stop there? Assuming $key never evaluates to 0:
DLmy $sub = $dispatch{ $key || 'default' };

DL Although there really is little point stuffing the coderef into a

DL not draw attention to it and just run the damned thing:
DL $dispatch{ $key || 'default' }-();

How about using a hash to keep track of which things you've already handled?
my %seen;
for my $value (@values) {
next if $seen{$value}++;
# Do processing with $value here.
