[Cython] Cython 0.16

2011-10-28 Thread Robert Bradshaw
With Mark's fused types and memory views going in, I think it's about
time for a new release. Thoughts? Anyone want to volunteer to take up
the process?

That'd be cool. However there are a few outstanding issues:
a) the compiler is somewhat slower (possible solution: lazy utility codes)
b) there's a potential memory leak problem for memoryviews with
object dtype that contain themselves, this still needs investigation.

As for a), Stefan mentioned code spending a lot of time in sub.
Stefan, could you post the code for this that made Cython compile very
slowly?

Yeah, I forgot about that. This should get resolved. Lazy utility
codes (perhaps breaking them up) would probably got us most of the way
there. Long term, I really like the "declaration caching" idea which
could be used for users .pxd files as well as internally.

I think this could be mentioned as a caviat rather than being a blocker.
