JFYI - this was why I had tried diverging from how the C api does things when
I originally started this series and what I had been trying to get at with my
original reply to you. The first design I had was basically just wrong, but of
course that's what patch review is for!

But yeah - that's kind of been our goal with a lot of this. Or at the very
least it's certainly been mine :). My priorities in order of importance:

 * Do the technically correct thing, and come up with a solution that provides
   as much or more error checking then the C side of things
 * Mimic C APIs where it doesn't compromise on the above point ^, just for
   ease of adoption

We already have a number of APIs (the WIP DRM bindings for instance) where we
diverge pretty substantially from how things would be done in C for the
reasons you mentioned.
