It's just you. ;-) Relax, you'll get over it.

But to return to the point brother FU brings up above, it's a question of what you want to emphasize. I think you're talking about how %hash gets populated (a terrible name for the variable, by the way; try to think of a better one), so I might even offer a hybrid:

my %hash;
for ( @{GetQueryTable('all_records_for_report', 137)} ) {
    $hash{ join(':', $_->{Computer}, 
                              $_->{Bulletin}, 
                              ( $_->{Product} || "" ), 
                              $_->{Status} ) }
          = $_;
}

If you can think of a more descriptive name for $_, it might clarify your intention quite a bit.

As Gerry Sussman explained,

"The important thing about a program is that it's something you can show to people, and they can read it and they can learn something from it ..."

It's only incidental that computers execute it.
