A team at Google (including Ken Thompson and Rob Pike) have release Go, an intriguing programming language that features extremely fast compilation.
The demo builds 120,000 lines of parsers and compilers in less than 10 seconds, on a laptop.
Also interesting: no inheritance and no overloading; instead, Go relies on lots and lots of templates.
(The debugger, apparently, will be called Ogle.)
Go is designed to have an extremely fast edit-compile-test cycle, which could make it an exceptional tool for building new hypertext tools and new literary machines.
