Subject: Re: class_eval doesn't find const_missing

If you add this code:

class Object
  def self.const_missing(constant)
    return "this #{constant} found in obj!"
  end
end

Then you get the following:

>> DummyClass.class_eval "NAME"
=> "dummy constant"
>> DummyClass.class_eval {NAME}
=> "this NAME found in obj!"
>> NAME
=> "this NAME found in obj!"

Not sure if that helps you much, but it seems that class_eval doesn't 
affect the constant lookup in the way that you'd like.
