in thread Foo is not a Bar, why?

The fact that inheirtance is done at all through a package variable is where the bolted-on part comes in. Perl just does too much OO stuff at runtime, which ends up being a very good Perl system but not a great OO system.

I wanted to explore how Perl's closures can be manipulated, and ended up creating an object system by accident.

    Would you consider Smalltalk a "not great OO system"? It does even more at runtime.

    Also, if Perl 5 introduced both packages and objects, how could objects be "bolted on"? Packages exist, in part, to make objects possible, without requiring OO coding!

    You will never hear me saying Perl's OO system is anywhere near half decent. But the problem pointed out by liz isn't an OO specific problem - it can happen with non-OO code as well.
