Excellent article, notwithstanding the fact that I dislike exceptions as an error handling mechanism as they make it way to easy to leave error handling to "whoever might be concerned". It is regular experience that exceptions usually bubble up to high and get poorly handled then, if at all. But as C++ allows for different mechanisms, that's fine.

So C++ exception handling code in a binary is irrelevant for performance. But what about mixing C++ code with code of other programming languages?
