Arc, if you don't know, is Paul Graham's "100 year language", or, more prosaically, new version of Lisp. It was heavily trailed on reddit (back when reddit was interesting), and an early version was released in January last year. But nothing much seems to have happened since then - the forum is virtually dead, and there's nothing new o...

I'm working my way through Graham's book "On Lisp" and can't understand the following example at page 37: If we define exclaim so that its return value incorporates a quoted list, (defun exclaim (expression) (append expression ’(oh my))) > (exclaim ’(lions and tigers and bears)) (LIONS AND TIGERS AND BEARS OH MY) > (nconc * ’(goodnes...
