> c++ don't support the required leeway of optimization transformations

What transformations do you think C++ doesn't support?

I've got a _lot_ of experience in C++ and I've found that it's almost always the case that whatever library being used needs to be rewritten for a small change. Rewriting libraries is rarely approved. And further, there's often very little unit testing being done towards that end too.

I meant automatic optimizations done by the compiler, and limitations imposed by the language semantics.
