He referred to a screencast and paper by Jonathan Edwards. The factorial example brings me back about 22 years to the hilarious April 1984 CACM issue where Dijkstra's "Goto Statement Considered Harmful" was "solved" using the COME FROM statement including its more advanced variants of ON x COME FROM label, COMPUTED COME FROM (See http://www.fortranlib.com/gotoless.htm ). That article culminated with a demonstration of the powerful of this new construct. The factorials function was built using COME FROM. Of course it took considerable effort to decipher the logic and understand what it does and how. When I look at Subtext, I get a similar feeling -- I cannot see and get it at once. I really have to work to decipher it. I guess the main reason for that is that us humans think in...
