To clarify, I think the main difference between Cython and Pyrex is  
that Cython aims to be a good Python compiler, not just a way to  
create extension types. I think most of the differences in philosophy  
can be traced back to this point.

Also, in terms of development, Greg wants to review and understand  
every line that goes into Pyrex, which makes it slower to accept new  
features. We still do quality review on the code contributed to  
Cython but the process is much more open. In this case it is more  
experimental, but I would say it's developing into more than just  
another branch of Pyrex. In terms of stability, I wouldn't say Cython  
is any worse than Pyrex in terms of finding bugs in releases, and  
both tend to fix bugs relatively quickly.
