deep interfaces

[matthewmueller]

This doesn't quite work yet:

package main

// VNode interface
type VNode interface {
    String() string
}

// Component interface
type Component interface {
    Render() string
}

type vnode struct {
    c *Component
}

func (v *vnode) String() string {
    return "earth"
}

func newComponent(c Component) VNode {
    return &vnode{&c}
}

type index struct {
    location string
}

func (i *index) Render() string {
    return i.location
}

func newIndex(location string) VNode {
    return newComponent(&index{location})
}

func main() {
    c := newIndex("mars")
    println(c.String())
}
