Forgot to mention...CLR does not have any support for dynamic invocation. Even the "dynamic" keyword in C# 4 is just porcelain over the DLR's dyncall pipeline. Oh, and I think it's important to note that no current release of the CLR (either .NET or Mono) does *any* runtime optimization whatsoever. Their "JIT" is basically "compile immediately before running with information available at that time". This means the DLR is almost certainly going to lag behind on performance, since they'll never be able to inline across dynamic call boundaries. invokedynamic, at least in the current work on Hotspot, can inline dynamic calls right now. - Charlie --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "The Java Posse" group.
