I just posted the final piece of the meta-circular Humus evaluator. "Evaluating Expressions, part 7 – Transactions and Exceptions" (http://bit.ly/fl6Z3O)
Throughout the series, I've had the opportunity to present a wide variety of powerful language constructs. Of course, concurrent evaluation/execution has been an ongoing theme. Pattern matching as part of the resolution of equations is one of my favorites. Single-assignment data-flow variables played an important role in automatic resolution of data dependencies. The lambda-abstraction mechanism is applied universally to support parameterization of not only expressions, but statement blocks too. I hope this series can serve as an interesting and informative reference. _______________________________________________ fonc mailing list fonc@vpri.org http://vpri.org/mailman/listinfo/fonc
