The problem, and I think this may have been touch on somewhere else in the thread, is that C++ can be really complex to wrap. So embedding a C++ library in another, higher-level language can be very tricky. It often requires wrapping the parts of the API you want to use in C.

I'm fine with low-level libraries being written in C++, but would hope that developers expose a C API around everything.
