# SuperStruct is an enhanced version of the Ruby Standard library {Struct}.
#
# Compared with the original version, it provides the following additional features:
# * ability to initialize an instance from Hash
# * ability to pass a block on creation
#
class SuperStruct < Struct

  # Overwrites the standard {Struct} initializer
  # to add the ability to create an instance from a {Hash} of parameters.
  #
  # @overload initialize({ Symbol => Object })
  #   Initializes the object with a key/value hash.
  #   @param [{ Symbol => Object }] values
  #   @return [SuperStruct]
  # @overload initialize([ value1, value1, ... ])
  #   Initializes the object with given values.
  #   @param [Array] values
  #   @return [SuperStruct]
  # @overload initialize(value1, value1, ...)
  #   Initializes the object with given values.
  #   @return [SuperStruct]
  #
  # @yield  self
  #
  # @example
  #   attributes = { :foo => 1, :bar => "baz" }
  #   Struct.new(attributes)
  #   # => #<Struct foo=1, bar="baz">
  #
  def initialize(*args)
    if args.first.is_a? Hash
