Re: Another Microsoft XML patent

It didn't occur to me until I read your post Mike... but what is
quickly becoming my favorite multi-purpose development language all
started with a paper headed by Erik Meijer, et Al. entitled
"Programming with Circles, Triangles and Rectangles"


At various stages and in various pieces the language concepts
presented in this paper have been known as X#, Xen, and Polyphonic C#.
 These have since been absorbed into what seems to be the next
generation, at least from MS's perspective, in the C-based family of
programming languages: COmega > http://research.microsoft.com/comega/
