require 'ostruct'
# 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">
