You are right David, I chopped the lambda and it still works ;-/

 I don't see how to get rid of the class variable as I am building a
hash from the repeated call to method_missing inside the block then
returning that through the instance_eval, if I don't use the class
variable, I will only get the result of the last call to
method_missing?
