Wouldn't a simpler solution be to use OpenStruct?

require 'ostruct'

hash={"my_attribute"=>"value"}
s=OpenStruct.new(hash)
puts s.my_attribute
 > value
s.my_attribute="new"
=> "new"
puts s.my_attribute

=> nil

And you get the freebie of creating new keys from the setter:

s.new_attribute="better"
=> "better"
puts s.new_attribute
 > better

Cheers,
