Racket, a multi-paradigm programming language belonging to the Lisp/Scheme family, has reached version 6.5, writes Ryan Culpepper on Racket blog. The new version adds several new features, including improvements to typed/untyped code interaction, faster iteration on hash tables and sets, and more.
The team behind Scala is adding an experimental version of macros in the forthcoming release version 2.10. Scala macros provide an advanced form of compile-time meta-programming.
As of version 11, macros will no longer be available in Visual Studio. This marks the first version in nearly a decade to not allow for crating ad-hock extensions to the IDE. Fully compiled extensions can still be created and new project templates are included to make that process much easier.
