Add Initializers section to properties documentation

[christopher-b]

I discovered the after_initialize hook while exploring how properties interact with the initializer. I'm sure other folks would find this useful.

It’s good to document this, but I think we should come up with a better example. I would use a coercion for this.

prop :name, String, &:strip

Perhaps something that compares two values against each other, like if we have min and max, we could raise here if min is greater than max.

Though even in that case, I would prefer to use a Range which will manage this or you. 😆

It’s hard to come up with good examples.

What about something like PersonRepository.add(self)?

Or even just

  def after_initialize
    # Your initialization logic
  end
