They don’t only say static types. They add classes, inheritance, subtyping, and virtual calls. Mind you, the difference between the last 3 is quite subtle.
So, since I’ve started nit-picking, Self is also OO and has prototype-based inheritance (as does javascript, but I’m not sure I’d want to defend the claim that javascript is an OO language).
Maybe because of projects that aren’t interested in the opinions of distro maintainers, let alone individual contributors.
