Objective-C++ is of questionable utility. At compile time, g++ 4 mode has
bugs 
that make some code that compiles when included from a .cpp file not
compile 
when included from a .mm file. At runtime, C++ exceptions and Objective-C 
exception can't mix unless you require Objective-C 2.0, Leopard, and
compile for 
64 bits (if I recall correctly), which makes error handling in
Objective-C++ 
tedious in the best case and extremely error prone in the worst case.

Honestly, a C++ library with a well-defined API is better off exposing
that API 
to Python (via boost::python). PyObjC and boost::python are much more
robust 
than Objective-C++ (and yes, I speak from first-hand experience).
