If a freezer method is defined for a given Dumper, the code assumes all classes can execute a method by that name. In my application, I want to dump some objects in a special way, while letting Dumper do its usual thing on other objects. A simple example shows the current behavior: ---------- use Data::Dumper; $x=bless {a=>1},'AnyClass'; $Data::Dumper::Freezer='any_method'; print Dumper($x); # fails. would prefer that Dumper ignore custom freezer if not defined ---------- Working patch files are available at http://isbiology.cvs.sourceforge.net/isbiology/AutoTools/AutoDB/patches/ We first reported this problem in Sep 2004. It looks to be related to bug 7009 reported by someone else. Any chance you can/will fix this? I'm in the process of cleaning up the package I distribute that needs the patch. If you aren't going to fix it, I'll bite the bullet and include the patched version (renamed) in the package I distribute. No big deal, but I hate to branch someone else's code unnecessarily. Thanks a lot for all you do! I really appreciate your hard work in making Perl such an immense force!! Best, Nat Goodman Senior Research Scientist Institute for Systems Biology

We are also running into this problem at our site, I haven't had the time to go develing into the Dumper code and create a fix for it. Would you be willing to supply/upload your patch? I know there must be others who'd be interested.

Greetings

The patch is available on CPAN at http://search.cpan.org/src/CCAVNOR/Class-AutoDB-0.092/patches/.  I've cc'ed my colleague, Chris Cavnor, who did the work and may be able to answer any technical questions.

All the best,
Nat
