[Bioperl-l] strange error after changing to RC1.5

[Allen Day]

I'm unable to test the code in PersistentObject.pm as I don't have biosql
set up, but you might try adding this to Reference.pm

  use overload 'ne' => sub { "$_[0]" ne "$_[1]" }

Please let me know if this fixes your error and I'll add this 'ne'
overload to all the Bio::Annotation::* classes on HEAD.
