I would love to have a robust enough C++ linter to be able to issue and check for rules like, "this type should not implicitly call its copy constructor".  I know some of those "gotchas" can be defended against using new C++11 features ("explicit"), but by no means all of them.  Linting for Symbol*::operator== is one of them that will never (?) be supported by the core language.
