As for optimizations, that is a quality of implementation issue with regards to compilers, not a language issue. This is a lie. Because C++ is such a poorly designed language, it is extraordinarily hard to make a (relatively) correct, let alone high performance compiler. Language complexity matters when you're writing a compiler, and C++ is every compiler writer's worst nightmare.
