I don't think it's in competition with Swig, which does C++.  There
are certain workloads in which C++ is the elephant in the room; we
don't address such workloads.  If you want some more motivation, the
initial goal was to access the large number of standard Linux/Posix
libraries that are C (or have a C interface), but are too hard to
access for ctypes (macros, partially-documented structure types,
#define for constants, etc.).  For this goal, it works great.

I fear parsing is merely the tip of the iceberg when we talk about
interfacing with C++.

A bientôt,
