Re: Problem w/overloading and Carp::confess

[blakem]

Adding a 'fallback' => 0 to your use statement prevents the deep recursion, but I don't think it will solve the actual problem.... (just pushes it further down the line a bit) Anyway, I could be wrong....:

use overload '""'       => \&asString,
             'fallback' => 0;

Thanks...Interesting results:

Operation `.=': no method found,
        left argument in overloaded package P,
        right argument has no overloaded magic at /usr/local/geospiza/
+lib/perl5/5.6.1/Carp/Heavy.pm line 91.

Looks as if in longmess() the string concat being done to turn the "arg" into something printable is lost... I was thinking that putting a check in longmess to see if stringify is overloaded and then calling overload::StrVal(), but I don't want to change Carp.

Apparently the recursion is being caused by

    if (ref $_) {
        # ...<snip>...
        $_ .= '';

in Carp.pm (or Carp/Heavy.pm).

I recommend that you copy Carp.pm to MyCarp.pm, and hack away at it. And maybe submit a patch when you're done.

Before submitting patches, I suggest downloading the development version of Perl because it may be (read has been) changed.
