Whenever you come across a new type, you should think about it from three perspectives:

  • Produce: how do I make a value of this type?
  • Transform: how do I transfom a value of this type into another value of the same type?
  • Consume: how do I destroy a value of this type?

In other words, think of types according to this picture:
