I\'d like to use named parameters when instantiating a Struct, i.e. be able to specify which ite

If you do need to mix regular and keyword arguments, you can always construct the initializer by hand...

Movie = Struct.new(:title, :length, :rating) do
  def initialize(title, length: 0, rating: 'PG13')
    self.title = title
    self.length = length
    self.rating = rating
  end
end

m = Movie.new('Star Wars', length: 'too long')
=> #

This has the title as a mandatory first argument just for illustration. It also has the advantage that you can set defaults for each keyword argument (though that's unlikely to be helpful if dealing with Movies!).
