Send channel through a channel with Go

I'd like to send a pointer to a channel through a channel. Is it possible in Go? How to define function that accepts such channel?

I tried:

func test() (chan *chan)
func test() (chan chan)

There is always some type associated with a channel. Let's assume that the type is T. A channel of T is:

chan T

A pointer to a channel of T is:

*chan T

A channel of pointer to channel of T is:

chan *chan T

A function accepting the channel of pointer to channel of T is:

func f(c chan *chan T) { }

Because channels are reference types, you probably don't need to use a pointer. Try using

 func (f c chan chan T) { }
