I think this is not possible using plain ruby because you can always
access constants in gobal scope.  If you control your plugins you can
use anonymous classes that register themselves somewhere. If the
registration is deleted their code is no longer accessible.

Other than that I guess you'll need to modify the interpreter in C
code - or create multiple interpreters.
