Below is a snippet of code with what I want to do. However it doesn't work as I would like. When I run it, I get

{"test1"=>{"name"=>"Test 1"}, "test2"=>{"name"=>"Test 2"}, "test3"=>{"name"=>"Test 3"}}
{"test1"=>{"name"=>"Test 1"}, "test2"=>{"name"=>"Test 2"}, "test3"=>{"name"=>"Test 3"}}

What I want is:

{"test1"=>{"name"=>"Test 1}}

{"test2"=>{"name"=>"Test 2"}, "test3"=>{"name"=>"Test 3"}}

What is the best way to get the class variable @@userVars defined in the sub-class (for each sub-class that sub-classes the super class).

Also is there a way to also get this capability via a module mixin?

Thanks //:)
