Hi,
I think this might be a bug (python 3.3 + cython 0.22.1):

val -= 1 << (len(term) *

Hey,
Here a pull request for element-wise array expressions for Cython:
https://github.com/cython/cython/pull/144
It includes the IndexNode refactoring branch as well.
This has been the work this last summer for the gsoc, with great
supervision from Dag, who helped steer the project in a great

Heh, so it seems if numpy doesn't understand the format string it
falls back to copying the array through the sequence protocol
(__getitem__ + len)? Since Cython can't convert multi-dimension C
arrays to objects, the memoryview getitem will use the struct module
(which really handles a subset of th
