title: Can methods be treated as regular subroutines?
body: <p>Is it possible to assign methods to variables and pass them around as arguments inside the class similar to subroutines?</p>
  
  <p>I know they're are accessible by either <code>self.</code> or <code>self!</code> (or whatever named explicit invocant) inside other methods but I'm wondering if it's possible to pass a method's code object as an argument to another method.</p>
