X++ Team Blog: Some highlighted changes for X++ Langauge

The X++ team did a post recently about some changes that are 'forthcoming' in the next release of Dynamics AX 2011.

Here is the direct link.:
Forthcoming changes to the X++ language

From the entry:
"We are continually looking at what we can do to make the value proposition of the X++ language stronger. We have identified that several changes are needed to avoid a number of runtime problems, and to make future alignment with managed languages possible. As always, we realize that any changes we make to the core language are a mixed blessing to people who maintain a large code base: On one hand the new semantics cause the compiler to catch more errors earlier, but on the other hand they will invariably cause changes to existing code."

A summary of the changes from that post are here.:

• Covariance vs. Contravariance


• No compilation error is issued when parameters without default arguments follow default arguments.


• The X++ compiler allows two methods with the same name where one is static and the other not.


• No visibility rules are enforced for access of overriding methods


• Abstract methods can be reached through a SUPER() call.


• Static constrictors are not diagnosed


• Abstract class implementation.


• Interfaces.


• Open array assignments.

So these are some great moves to help bring X++ forward into some of the same great functions, abilities and desires for X++.

I can't wait to see more from the X++ team blog, thanks for the update!

Check back soon, as more great post are to come.
