[go-nuts] go: Passing a member function as an argument compile error

[Greg Bostrom]

I just posted this on on openstack.
Maybe someone here knows the answer?

I would expect this to compile after watching this talk by Rob Pike 
https://www.youtube.com/watch?v=HxaD_trXwRE&t=1830s 


package main

type StateFunc func(*M) StateFunc

type M struct {
    start StateFunc
}

func New(start StateFunc) *M {
    return &M{
        start: start,
    }
}

func (m *M) foo() StateFunc {
    return nil
}

func (m *M) Start() {
    go m.run()
}

func (m *M) run() {
    state := m.start
    for state != nil {
        state = state(m)
    }
}

func main() {
    m := New(foo)
}


It fails with

prog.go:31:14: undefined: foo
