Any insight on Microsoft's new M programming language?

Does anyone have any insight on microsoft's new M programming language? Why? What type? When? What?

From stackoverflow

• There's this gathering in a couple weeks? PDC, I think it's called? :)

• It's "D" - not Digital Mars D - renamed.

  For more info.

• I'm no insider, and the Mary Jo Foley article below is from June (so there must be considerable updates), but in the article Mary explores the rumours around a new Declarative Model-driven language that she (and if memory serves, .NET Rocks) referred to as D.

  I'm going to take a flyer on connecting the dots here, and I could be completely wrong, but perhaps the Declaritive Model-driven language formerly known as D is now called M?

  Back in the summer (again, there have got to be updates), one of the (many) goals of Oslo was to introduce a UML-like language that would actually be worth the effort, as the Model Diagram would be kept in synch w/ the code all of the time. (As opposed to one of those nice-looking, not-quite-reflective of current reality, Visio UML diagrams)

  ICR : D is indeed now called M.

• Don Box gave a presentation at PDC.

  If you don't have time for a video, I found this summary on Oslo to be helpful.

• "M" stands for the language family that comes with oslo. It basically consists of two languages and a data representation format.

  • MSchema Defines schemas for data instances. Quite comparable to XSD and DTD.
  • MGraph JSON-like format for capturing concrete data instances.
  • MGrammar Defines grammars for textual DSLs. Could also be looked at as a Unicode-to-MGraph-tranformation language.

• I've written a long article about Oslo, in which I explain why Oslo is confusing, and hopefully explain where Microsoft is headed with it.
