You do have to instantiate that struct, and you can do it with.... a beautiful NewCreateUser(dep1, dep2, dep3, ..., dep20) *CreateUser {...}. This is essentially what he recommends with his "func newMiddleware() func(h http.Handler) http.Handler".

I'm pointing out that this is basically "passing all the deps at once" with extra steps but no functional benefit; they are at best aesthetic, at worst confusing.

I'd like a world that sacrifices a bit of aesthetics in order to erase ambiguity or confusion. So instead of putting your deps in a struct that's a param, or putting your deps in a parent closure, I'd like to put them in the function params.

Though I will admit that if I had to choose, I'd use (and have used) the closure approach most often.
