You can as well use a Hash instead.  You might also want to look at 
OpenStruct, which might help you, too.  An OpenStruct happily accepts every 
getter or setter when invoked:

>> require 'ostruct'
=> true
>> o = OpenStruct.new
=> <OpenStruct>
>> o.foo
=> nil
>> o.foo = "bar"
=> "bar"
>> o.foo
=> "bar"
>> o
=> <OpenStruct foo="bar">

Kind regards
