Thanks, that's helpful. Am I reading it right? Are you running the 
python process embedded in your C++ app? (rather than extending?)

OK, so you've now got a view of the data from the valarray. Nice to know 
this works, but, of course, fragile if the valarray is re-sized or 
anything, so it probably won't work for us.
