Ja. This is a sweet combination. The Joy of Swig is we can declare some 
parameters as basic types, but others as raw PyObjects. Then we can have our 
way with these.

And using CXX, we wrap these objects in high-level C++ methods. Not the 
low-level fragile C. The effect compares favorably to ATL for VC++ and 
ActiveX.

But there's just one little question here. (Hence the buckshot of list 
servers.)

If we pass a multiarray into a function expecting a PyArrayObject, how then 
do we add new elements to it? I tried things like 'push_back()' and 
'setItem()', but they either did not exist or did not extend the array.

Am I going to have to generate a new array and copy the old one into the new?
