You're doing something really dynamic; don't think I'd call it
inherently evil though.
All you have to do is use a variable in the inheritance syntax, it's
really quite simple:
superclass = TraceablePointSet if tracing else PointSet
class IDPointSet(superclass):
#body code here
#use same trick for MicroArrayPointSet
