I wrote something a few months ago about this for the SAGE programming
guide, about why Pyrex is by far the best choice *for us* as compared to
the other options.  See section 5.1.2 of the programming guide here:

  http://sagemath.org/doc/html/prog/prog.html

I think SWIG, boost, and Pyrex all have their optimal domains of application.
E.g., SWIG is better if you want to expose an existing library to more
than just Python.   Pyrex is the best when raw speed is absolutely critical,
but working directly in C (against the Python/C API) is too time consuming
and bug prone given the size of the project.
