E.J. Dijkstra in "A Discipline of Programming" proposed multicase "do" and "if" constructs; the former looping, the latter single-shot. The "guards" he proposed were strictly boolean expressions determining which, if any, of the guarded statements would be executed. If no guard proved true, the if statement would fail (abort), the do statement would stop iterating. If multiple guards proved true, one would be picked at random from the succesful ones.
I was very disappointed when Go stayed with the more conservative if and for, although I could not make any proposal on how to implement Dijkstra's ideas in a Go-like language. It's regrettable, in my opinion; I found the proposed uniformity very appealing. Lucio. -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
