[Cython] h5py build broken by 0.20b2

[Julian Taylor]

Hi,
a h5py cython file fails to build with cython git head and 0.20b2.
It works with older versions.
This file fails

The offending file seems to be:
https://github.com/h5py/h5py/blob/master/h5py/h5p.pyd

cython h5py/h5p.pyx
Error compiling Cython file:
------------------------------------------------------------
...
from _objects cimport ObjectID

# --- Base classes ---

cdef class PropID(ObjectID):
    """ Base class for all property lists """
   ^
------------------------------------------------------------
h5py/h5p.pxd:17:4: Executable statement not allowed here
...

it was introduced in cython around this commit:
b6b5152f386ddae503674cc26200a547f3b4c8b0
properly handle expressions at the beginning of func/class/etc. blocks


Is this an intentional change? I did not see anything related in the
CHANGES.rst of the 0.20.x branch.
Please advise if this is a bug/regression in cython or
bug/required-change in h5py.


Note, I know neither cython nor h5py, Yaroslav Halchenko just
encountered this issue while testing packages with 0.20b2 in Debian.
Let me know if you need more information.
