> PHANtom was built taking into account recent advances in aspect language features such as dynamic advice rescheduling, reentrancy management, and scoping strategies for deployment. The advanced features are not all implemented yet, but the 'normal' features work and are well-tested (about 130 unit tests) so we are relasing it to the world for you to try out. We hope PHANtom can help you to solve some cross-cutting code problems.
