in reply to Unexpected Data::Dumper results

Probably not what you would call elegant but if you execute it twice, it works... at least in this case. Just like LaTeX... 

$VAR1 = {
          'shared' => \'true',
          'parents' => [
                         {
                           'isRoot' => $VAR1->{'shared'}
                         }
                       ]
        } for (1..2);
print $VAR1->{parents}->[0]->{isRoot},"\n";

    Executing twice seems like the obvious solution... but there's some loss of data integrity.

      ...and, as with LaTeX, there might be situations where two runs are not enough...
