In Go, I'm going to avoid using 'any' as an actual type

Jokes aside tho, I agree—the "anything goes" (pun intended) approach in dynamic programming languages is so annoying. Using "any" in a typed language is like "go"ing back to dynamic style, which many already are trying to escape.

Enough puns for today!

  // You can edit this code!
  // Click here and start typing.
  package main

  import "fmt"

  func main() {
   duck := Duck{}

   identity(duck).quack()
  }

  func identity[T any](t T) T {
   return t
  }

  type Duck struct{}

  func (d Duck) quack() {
   fmt.Println("quack")
  }

  /*
  quack

  Program exited.
