We should probably provide an example of preprocessor hackery that lets you use these interfaces and remain backward compatible as far as possible. Maybe even a little .h file which we can suggest extension authors bundle with their extensions.
I would be delighted if somebody else did that. As I age, I find it increasingly difficult to do more than 103 things at once <wink>.
I hope you don't mind if I wait a few weeks. Though I guess I wouldn't be aiming for a moving target now, I'll feel safer in a month or so...
I'd wait too, if I were you -- the only thing we've actually finished so far are the hard parts <wink>. I hope /F and MAL will help too, since they know more about writing Python extensions in real life than anyone except the Queen Mum.
