Hi all,
given the overwhelming lack of negative feedback on the latest alpha
release, and the recent changes that made it into the master branch, I
think it's time for a first beta release.

Either I don't understand you, or you don't understand Eigen. Eigen overloads
operator=() to circumvent need for temporary arrays. It is *no

There is no such thing as "Eigen library". Eigen is fully implemented in
header files. Cython would just generate C++ code that

Not according to the documentation.

Which is ok for many users, definitely those who only run their own code
locally. And the others can eventually use a different backend.

That would be awesome (I love ipython notebook).

No, but I could make one :)
ipython notebook?

But using Eigen will taint the output with Eigen's license, since the Eigen
library is statically linked. OTOH, Cilkplus is just a compiler extension
for C and C++.
AFAIK, it is currently available for Intel C++ and Clang (also by Intel)
and GCC 4.9. On MSVC I believe it requires Intel Parallel S

Cython does not do an error here:
- i is recognized as private

If you need thread local storage, use threading.local()
I agree that scoped cdefs would be an advantage.
Personally I prefer to avoid OpenMP and just use Python
