Hi Vijay, thank you for the information. What I would be interested in is are you thinking about beeing able to convert/call Java clases/methods from X10? Given that there are plenty of libraries it would make sense to be able to reuse existing java libraries from within X10, right?

Are you working with the JikesRVM to support X10? Does enhanced here state the fact that X10 will have its own binary format / bytecodes? > Our goal continues to be to develop a simple, clean modern OO language > for concurrency, distribution and heterogeneity.

Or was there a problem that the Scala static free syntax did not allow you to do. IMHO static methods are a feature of constant debate in the OO communities... > Best, > Vijay > > > > > > ------------------------------------------------------------------------------ > Crystal Reports - New Free Runtime and 30 Day Trial > Check out the new simplified licensign option that enables unlimited > royalty-free distribution of the report engine for externally facing > server and web deployment. > http://p.sf.net/sfu/businessobjects ------------------------------------------------------------------------------ The NEW KODAK i700 Series Scanners deliver under ANY circumstances!
