module Register
  # This implements the creation of a new frame object.
  # Or to be more precise, it makes the frame available in a register, as the message (any message)
  #  carries a frame around which is reused.

  # Just as a reminder: a message object is used to send and holds return address/message
  # and arguments + self
  # frames are used by a method and hold local and temporary variables
