[Cython] __next__ | not being able to use cpdef

[Jelle Feringa]

Hi Dag Severre,

Thanks, I will read through the "Comments on example code" thread,  
sorry I missed out on that.
Thanks also for the example you gave.

I did not understood why its necessary to wrap the do_curvature call  
in Cython though: the call is close enough to C++ execution speed.
The API I'm working with is *huge*, in C++ and already wrapped in SWIG  
( using introspecting in gcc_xml ) , so moving it to Cython is really  
not an option.
If the function is fast, why is it necessary to move it to Cython?

Like Robert points out: I can measure a 500*500 loop in Python, it  
would be hard to measure it in Cython.
That's the bit I'm interested in ;')

Perhaps my question is naive, but I'm trying to understand why.
