Have Someone Else Stare at Your Code

Two months after writing the above code -- and after I had spent a couple of weeks preparing this talk -- I showed this code to a Perl expert who noted that in both instances of _calculate_row() I was dereferencing, and then taking a reference to, something that was already a hash reference.

Top part before and after:

        _calculate_row( \%{ ${$period}{$_} } );

        _calculate_row( ${$period}{$_} );

Bottom part before and after:

        _calculate_row( \%{$period} );

        _calculate_row( $period );
