IIRC, believe the SIP notation has a symbol (%) that tells it how to manage the
ownership, whether it become python owned or is C++ owned. I am absolutely
certain they have it, and it is some kind of decoration. I've not used SIP in a
while.
Anyway, I am going to start my work in Jython using the Java version. If or
when the CPython version comes about let me know. I should just need to
reinvoke the code in that context and see how it compares.

Subject: Re: [Wt-interest] Where's the python love?
To be correct most of the binding work has been done by Geert, I only added the
clang frontend and got the project up to date somewhere in Q1 of this year.
Doing the bindings ourselves, and encountering all difficulties (memory mgmt,
thread handling, inheritance, object ownership, ...), I'm a bit sceptic that a
generic purpose binding generator would solve them all out of the box. But as I
said, I'm definately willing to take a look at SIP.

Wim.
