This is how JRuby has worked since 1.0, though we do have a small shim class between the call site and the callable object to handle lookup, caching, and method_missing logic. But other than that it works very well, and our dispatch performance is quite good. > theoretically this can be done with Atilla's MOP too, but we would have > to use the get method to get something callable and then call it... only > that we need to transport information like caller, callee, arguments and > of course methodname. And I am not sure how that would be done. Atilla's Dynalang project could easily be modified to support the "callable" mechanism, and indeed would need such a modification to support both JRuby's current dispatch logic and invokedynamic. I'm hoping to start contributing to Dynalang very soon. > Of course suppporting Atilla's MOP as an interface to Groovy's MOP is a > different story, since we can write a bunch of adapter classes and be > done withit. Of course the use is then "limited" to interlanguage calls This is a good initial goal, and we've started looking into doing this for JRuby as well. - Charlie _______________________________________________ mlvm-dev mailing list mlvm-dev@openjdk.java.net http://mail.openjdk.java.net/mailman/listinfo/mlvm-dev
