Yes, the remaining part is a hurdle, but hopefully not a very big one. The interface will always be slower, but hopefully you won't have to interact with it muc

Yes, the remaining part is a hurdle, but hopefully not a very big one. The interface will always be slower, but hopefully you won't have to interact with it much (you almost never do with scipy). We have a cunning plan on how to make the numpy interface faster though, stay tuned [To recap: generic-cpython-extension-border-crossing will always be slower, btu maybe we can do hacks for numpy]
