This fails for the command: python cythonize.py
[where python is python.exe from python36 install directory]

But works for the equivalent command: cython -a --cplus -3 --fast-fail main.pyx
[where cython is cython.exe from python36 scripts directory]

The two commands are actually not equivalent because you are not enabling Py3 mode in the first. Shouldn't make a difference here, though...

Nice catch. That was the problem.
Adding #cython: language_level=3 to the pxd file solved it.
Thanks!
