thanks, but this didn't change the time much at all (something like . 
5 ms out of 20ms).  I was following the example in the cython docs  
Early Binding for Speed section, but now I see it got updated to cpdef!

I'll keep hacking away at it.  Perhaps I'll try a smaller example, to  
see the difference between lookups in classes and in structs, if that  
really is the issue.

Is there a better way to find speed bottlenecks than the "comment out  
and re-compile" method?  :)

		thanks,
