creates a new instance and invokes ‘call`. Any positional argument is forward to `call`. Keyword arguments are either forwarded to the initializer or to `call`. If the keyword argument matches the name of property, it is forwarded to the initializer, otherwise to call.

ruby2_keywords def call(*args, &block)
  # This is an extremely complicated case of delegation. The method wants
  # to delegate arguments, but to have control over which keyword
  # arguments are delegated. I'm not sure the forward and backward
  # compatibility of this unusual form of delegation has really been
  # explored or there's any good way to support it. So I have done
  # done something hacky here and I'm looking at the last argument and
  # modifying the package of arguments to be delegated in-place.
