[ANN] NamedStruct, a gem that allows you to initialize Structs with keyword arguments

I found myself repeating something like this in all projects that I'm
working on:

class MyStruct < Struct.new(:x, :y)
  # Allows initialization via keyword arguments (Ruby
  # only supports positional arguments by default)
  def initialize(**kwargs)
    super(*members.map{|k| kwargs[k] })
  end
end

Thought it'd be worth extracting into a gem:
