How about parallel processing of elements stored in one of the java.util.* collections? Could we make the Groovy each(), collect() and such methods leverage multiple threads to speed them up? In fact, it is very easy. I wrote briefly about the new concurrency enhancements planned for Java 7 under JSR-166y earlier. I'm still happily experimenting with the library and here's how you could seamlessly employ ParallelArrays to speed up your Groovy collections. Thanks to Groovy meta-programming capabilities we will replace some of the original GDK methods on collections with parallel implementations. - Avi Flax
