Howdy!

Well...that's interesting.

I changed Set::Scalar::Valued to something else and it all worked fine. I tried two unrelated packages (CGI and Net::Server).

In the debugger, I find more "odd" behavior. I think I may need to examine Set::Scalar::Valued to see why, in:

        # Flatten arg list
        my @arg_objs;
        while (my $arg = shift) {
            if (ref($arg) eq 'ARRAY') {
                push(@arg_objs, @{$arg});
            } else {
                push(@arg_objs, $arg);
            }
        }

(being in Object::InsideOut::Foreign::inherit) that stepping into "while (my $arg = shift)" takes me directly to Set::Scalar::Base::size with the object that shift() would have consumed being passed in.

Ick. Examination of the entrails of Set::Scalar reveals nothing to me as yet. At this point, I'm puzzled more.
