[C++-sig] Need strategic advice designing Boost/Python program

I think you can have both. Only the implementations tendy to
become dirty if you go for speed.

This is exactly our situation. You may want to look at the
"scitbx", which is a library for a bigger project (cctbx.sf.net).
It is built from day one on top of Boost.Python. There is a little
bit of an introduction here:

  http://cci.lbl.gov/~hohn/scitbx-tour.html

The backbone of our system is the array family, with the most important
types being reference-counted C++ arrays (af::shared, af::versa):

The pages are a bit rough and slightly out of date. You can get
standalone scitbx bundles here:

They come with and without Python included and have no external
dependencies (other than an OS and a C++ compiler).
