Thanks very much for your feedback! Since the chapter in under a CC
licence, you are welcome to submit your proposal as a Pull-Request. :D

The reason why I wrote  the loop in C is so that the cython example
synergieses with the others. The ideas is, that you have an already
existing code-base that has a function which has such a signature.
Ideally, your proposal would be an improvement, where the original
example stays in place and you develop the improvement including reasons
as to why it is better. ;)
