Thanks. So is Clone called implicitly? There's no call for it, even if
that's the reason __init__ is called twice. Could I just use a pass
statement in the Clone body, or does it need functionality?

Also, do you know why it didn't work when I set the recursive flag and
called Validate on self?

Thanks.
