This is kinda missing the point; each handler needs a lot of deps to do it's job, and the most obvious place to put them is in the parameters of the function. That is what I want. I do not want more indirection for aesthetics; I want clarity, even if it's brutal clarity.

Whether all the deps are in the method receiver (the parent struct) or in a struct that's a param; it's all just more indirection to hide all the "stuff" that we need cause we think it's ugly. I dream of a world where we don't do that.

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.
