Where did keyword2 go? Perhaps this was a design decision. If not, adding the line @{$hash{$currentkey}} = (); into the if( $inkey == 0 ) block does the trick.

P.S.: In order to make Data::Dumper print very nice output, pass it a hash reference, as in Dumper(\%hash). Then the output is as follows:

$VAR1 = {
          'mykeyword3' => [
                            'baz3',
                            'foo3',
                            'bar3'
                          ],
          'mykeyword2' => [],
          'mykeyword1' => [
                            'foo1',
                            'bar1'
                          ],
          'mykeyword4' => [
                            'baz4'
                          ]
        };

P.P.S.: Can some enlightened monk tell me the preferred way to "touch" an array (reference). That is, if I only want to clear an array if it doesn't already exist (see my @{$hash{$currentkey}} = (); addition above). The snippet push @{$hash{$currentkey}}; works but produces a Useless use of push with no values warning.
