It's useful if the caller is expecting an Object (or any interface) and the ultimate callee is producing a reference type. In that case, there is no need for any conversion work in the return, and therefore we can use a more efficient framless, tail-calling conversion. Of course the general case must deal with return value conversion also. (I'm also keeping an open mind about support for multiple value returns, eventually. The multiple values would be reified to a ricochet adapter using the same ArgumentList type.) >> I think they would be really great, but I don't know if they are >> doable >> and how muich trouble they give to VM implementor. > > I wouldn't worry too much about the VM implementer :) (...muffled shriek...) -- John --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "JVM Languages" group.
