I recently learned about the Tim Holy Trait Trick as one way to dispatch on “groups” of types outside of a type hierarchy. This seems more general to me than dispatch based on type hierarchy, but I’m not sure. Are there things which are easier to do (or settings which are better suited for) using t…

Julia’s type system together with multiple dispatch is already very powerful for generic code and should be able to handle the majority of cases, so it’s more like traits are an overkill for most tasks. For example, instead of defining a new trait for two types to dispatch on, you might as well just…
