Currently when you have reference to other scripting units, all variables and methods are avilable by name
eg :- You can refer ExternalUnit having //USEUNIT or 'USEUNIT
ExternalUnit.RoutineA() and RoutineA() both can be used, where RoutineA() is defined in ExternalUnit.
using just method/variable name is fine, but may course readability and conflicts.
I would like to have option to restrict calling only qualified references like ExternalUnit.RoutineA()
