invokedynamic actually isn't faster than reflection per se, if you are able to store the reflection method points in a structure to use for later. Actually, if you play with invokedynamic (it's not easy) on the current iteration of the officially released Oracle JDK, you will find that invokedynamic is a bit slower than calling reflected methods! I understand that this was fixed in trunk, and the next release of JDK 7 will have invokedynamic be faster. -- You received this message because you are subscribed to the Google Groups "Clojure" group.
