I don't know why people make it so complicated. :-) All these are easier 
than other approaches suggested so far:

Foo = Struct.new(:attribute, :another_attribute)
class Bas < Foo
end

class Bas < Struct.new(:attribute, :another_attribute)
end

or even

Bas = Struct.new(:attribute, :another_attribute) do
   def another_method() end
end

Kind regards
