  def p.primary_email
    personal_email
  end

Or closer to the pointer solution you want:

  p.primary_email = lambda { p.personal_email }
  p.personal_email = 'me@gmail.com'
  puts p.primary_email.call

The lambda expression corresponds to the address operator, the .call
corresponds to a pointer dereference.
