My point was that only reason to use C++ is when you want repeatable performance which implies that you will not do things that are against this goal (and in fact C++ makes various tricks to achieve this goal trivial, eg. per-timestep heaps) My other point was that for anything other you do not want to use C++. Edit: and also "when used in certain ways" is exactly the problem with C++ I tried to point out. The language and it's interactions with real implementations is simply too complex for any kind of useful analysis.
