go - Is there a better dependency injection pattern in golang?

Question

Given this code:

package main

import (
    "fmt"
)

type datstr string

type Guy interface {
   SomeDumbGuy() string
}

func (d *datstr) SomeDumbGuy() string {
  return "some guy"
}

func someConsumer(g Guy) {
  fmt.Println("Hello, " + g.SomeDumbGuy())
}

func main() {
    var d datstr
    someConsumer(&d)
}

Is the wiring of components together that's done in main the right way to wire a dependency together? It seems like I'm over using this a bit in my code. Is there a common pattern better than this, or am I overthinking it?
