Dear monks

I was hoping you would be able to help me understand the following error handling code 

my $rows_deleted = $dbh->do(q{
      DELETE FROM table
      WHERE status = ?
  }, undef, 'DONE') or die $dbh->errstr;

[download]
I believe that dbh->do will retrun undef if there is an error, but what is the result of assiging an undef to a varible? I guess it must be false otherwise the or test would be passed and the die statement wouldn't happen? I thought an assignment was always true

many thanks
