We describe a form of method-call interception (MCI) that allows the programmer to superimpose extra functionality onto method calls at run-time. We provide a reference semantics and a reference implementation for corresponding language constructs. The setup applies to class-based, statically typed, compiled languages such as Java. The semantics of MCI is used to direct a language implementation with a number of valuable properties: simplicity of the implementational model and run-time adaptation capabilities and static type safety and separate compilation and reasonable performance. Our implementational development employs sourcecode instrumentation. We start from a naive implementational model, which is subsequently refined to optimise program execution. The implementation is assessed via benchmarks.
