Re: Apache::Session & Math::Currency thawing issue.

[Ken Williams <ke...@forum.swarthmore.edu>]

This is a followup to an old message from June 19, to tie up loose ends.

A simple test case shows that the problem described here is a bug in
either Storable.pm, overload.pm, or Perl.  Freezing and thawing an
object seems to destroy any overloaded operators of that object.  I'm
starting to pursue the issue with the authors.  I'll post here for
completeness if I get the issue resolved.
