This is distinctly different, however, in that it adds the accessor
methods to the Foo class, not the instances. I have no idea what Mr.
Kleb wanted, but given that he's adding accessors based on hashes
passed to each instance, my guess was that he would want a unique set
per instance.

  f1 = Foo.new :name=>'whee'
  f2 = Foo.new :age=>12
  p f1.age 
  #=> nil

Is the above result desirable, Bill?
