I agree with Merlyn that just giving names is the easiest way, by far. However, if you really want to get into some deep, dark perl voodoo, check this out: 

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

sub test1 {1};
sub test2 {2};
sub test3 {3};
sub test4 {4};

sub findsym {
    no strict 'refs';
    my ($pkg,$ref) = @_;
    foreach my $sym ( values %{$pkg."::"} ) {
        return *$sym{NAME} if *{$sym}{CODE} && *{$sym}{CODE} == $ref;
    }
}

my @tests = (\&test1,\&test2,\&test3,\&test4); 
foreach my $subref (@tests) {
    my $name = findsym(__PACKAGE__,$subref);
    print STDERR "Test $name\n";
    print $subref->() . "\n";
}

I recently discovered this kind of thing poking around in the guts of Attribute::Property and Attribute::Handlers and thought it was pretty cool. I've never even seen a print reference to the {NAME} property of a typeglob.
