Well, now that I read it better, maybe there is effectively something to 
worry about the Pyrex future ;)  I just wanted to point out that Pyrex 
is still a good piece of software and much kudos should go to Greg as 
the originator of the idea.

important to point out that he has been always fast in fixing real 
problems (with his own patches or contributed ones).

and pushing Pyrex forward.  And in fact, the Cython guys seems to be 
commited to maintain compatibility with future Pyrex, which is really

I'm not saying the contrary, indeed!
