OK there is some static dispatch in regular functions with respect to argument overloading, e.g. f(int) and f(char), or obj.f(int) and obj.f(char).

But I think what is more commonly thought of as "static dispatch" is various template programming patterns, as in the blog post, which are more flexible, and has equivalents in Rust AFAIK.

Overall it does feel like there are too many similar mechanisms that look extremely different!
