I like the proposed ideas, but removing things and making breaking changes might be going too far. Compilers should be smart enough to help. I wish g++ and clang had a "-best-practices" compiler flag: -Wall is not enough. But since you will never get everyone to agree on what subset of C++ is best practice, and what dark corners should be avoided, maybe a set of -Wbest-practice-this and -Wbest-practice-that flags that allow you to pick and choose. Warn yourself when you do things that are not warning-worthy but you nonetheless want to avoid.

EDIT:

For examples, I'd love to have -Wold-style-cast on all of my compilers. The nullptr example in the article is good too, maybe call it -Wold-literal-null? It would be nice if my compilers could give me hints when std::move might be appropriate, if I might be missing a copy or move ctor, or when I could consider using initialization instead of assignment for members. Maybe this is more of a job for the static analyzer and not the compiler--dunno.

Like this?
