The bundle _classes_copy() permit to have the exact result classes from other ones.
Example:
If myClassA is a result class of a successful action, the result classes will be myClassA_kept, myClassA_not_repaired,etc...
The use of the bundle _class_copy() will permit us to have the same result classes but with different names. _classes_copy('myClassA','myClassB') will create the result classes: myClassB_kept, myClassB_not_repaired,etc..

But sometimes, this is the inverted classes we wants, that is to say with the same example: _classes_inverted_copy('myClassA','myClassB') with the result: myClassB_repaired, myClassB_not_kept,etc..
