I'm saying:

- main constructor is easily available from the main type's docs,

- option type is easily available from the main constructor's docs,

- all option funcs are easily available from the option type's docs (because in fact these option funcs are constructors for the option type).

Excerpt from grpc godoc index:

    type Server

    func NewServer(opt ...ServerOption) *Server

    ...
    ...

    type ServerOption

    func ChainStreamInterceptor(interceptors ...StreamServerInterceptor) ServerOption
    func ChainUnaryInterceptor(interceptors ...UnaryServerInterceptor) ServerOption
    func ConnectionTimeout(d time.Duration) ServerOption
    func Creds(c credentials.TransportCredentials) ServerOption
    etc...

One more hop compared to a flat argument list, that's true. But if you only commonly use maybe 0-5 arguments out of 30-50 available, it does not look like a bad deal.

I’m not confused about what it is, I just don’t like it. It’s a lot of ceremony for very little gain.
