I'll check it out. Thanks

Ahh. Didn't realize the __init__ was required to trigger that. I did
have it 'working' without the init after I added an
implicitly_convertible< < smart_ptr<X_Wrapper>, smart_ptr<X> >(). It
would append but I hadn't verified that all the reference counting was
working as expected.

I will add the __init__ as well.

Many thanks for your help.
