why the use of http.HandlerFunc

[rickb777]

Why does Negroni use both http.Handler and http.HandlerFunc in its API? It's rather inconsistent.

func New(handlers ...Handler) *Negroni

compared with the third parameter in

type Handler interface {
	ServeHTTP(rw http.ResponseWriter, r *http.Request, next http.HandlerFunc)
}

[devdinu]

negroni.Handler interface will have

  ServeHTTP(rw http.ResponseWriter, r *http.Request, next http.Handler)

instead of http.HandlerFunc.

and we 'll need a new release. But this will affect the consumers when they upgrade.
I can change it and raise a PR if owners/maintainers give it a go.

I agree that it is a little inconsistent, but I hesitate to modify this part of the API until a version 2 given the severity of the breaking change.
