module Mirrors
  # Methods here follow the pattern of:
  # <target>_<instance or singleton>_<invoke or method>
  #
  # * target is the owner of the method
  # * instance or singleton indicates whether we want an instance method or a
  #   singleton method from the target
  # * invoke calls the method on a receiver, which must be compatible with the
  #   method. method returns the method to bind to whatever receiver you want.
