I'm hoping to get to JavaOne, in which case it would be great to get together. There is lots of opportunity for collaboration. > And since we're at that, how do you deal with > platform-dependent code?

Fan defines the standard APIs as Fan classes, then where appropriate stubs some methods as "native" which are then implemented in Java and C#. The sys pod which defines the core is entirely written in both Java and C#. We tried various other approaches, and in the end that seemed the most straight forward. > The part that I find really interesting in Fan > is the approach to concurrency.

For example message passing is defined as methods on the Thread class. Fan's switch statement is a bit more powerful than Java, but doesn't provide full pattern matching like Erlang or Scala (that is something we'd like to do though). > Until the JVM is brought up to date with respect to basic > functionality like tail calls, I'm afraid you won't be seeing > any production-quality innovation along the lines of F#. Can't tail calls be generated by the compiler with an in-method jump? I guess it would be tricky to push/pop the stack, but it seems feasible. --~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "JVM Languages" group.
