in thread How to view contents of a blessed Regular Expression?

Hmmm, doesn't work for me using ActiveState Perl 5.6.1. I wonder if it makes a difference that I'm blessing it in the context of an eval{} function like so: 
eval { bless qr/$pattern/, ref($class) || $class };

I'm finding this all very confusing and I should probably just forget about such a minor thing.

    qr// gives you a reference to a scalar that is already blessed into the Regexp package. So you are reblessing it which stops Regexp methods/overloads from working on it after that point. Stringification is a Regexp overload and so no longer works. If you want stringification again, then you'd need to provide such a overload via your AltRegex package.

      But if you inherit from Regexp, wouldn't the overload be inherited as well? i.e. this works:

      use strict;
$^W++;
package A;
use overload '""' => sub { overload::StrVal(shift) . 'xx' };

package B;
@B::ISA = 'A';

package main;

my $a = bless \(my $aa = 'abc'), 'A';
print "$a\n";
bless $a, 'B'; # re-bless
print "$a\n";

        Well, as I thought, this is beyond my grasp right now. I think I'm getting too bogged down in the details. I'll bookmark this node and come back to it in a couple months.
