Subject: dynamically assigning instance variables (redux)

I need a modern answer to Daniel Berger's 2002 post,

  http://blade.nagaokaut.ac.jp/cgi-bin/scat.rb/ruby/ruby-talk/39534

  Is there a way to dynamically assign instance variables?

  class SomeClass
    def initialize(hash)
      hash.each do |key,val|
        @#{key} = val # Doesn't work
      end
    end
  end

Actually, I'd like the assignment and make them attr_readers too.

Nearly meta-programming clueless,
