The language (and the features) presented in this presentation are from Fortress, which Guy and other Sun researchers have worked on for some time. On the project page one can download Fortress 1.0 and also check out Fortress 1.0 specification: http://projectfortress.sun.com/Projects/Community/

It's a pretty ambitious project and it looks like they are going to succeed. The focus of the language is to create a new Fortran, but personally, I think the scope and the ambition of Fortress are bigger. Viva la Guy Steele :)
