2012-04-04 Thread Luke Vilnis
I had to instantiate the "map" function explicitly, and couldn't use "cons?" because it returns whether something is a Pair, not a Listof - but the following works: (: cars : (All (A) (Listof (Listof A)) -> (Listof A))) (define (cars ls) ((inst map A (Listof A)) car (filter (λ (x) (not (empty? x)

Stay in the scheme sphere long enough everyone has their SRFI moment and one concerning SRFI-19 in particular. Here I refer to the, "that's it, I can't stand no more, by god, this time I'm going replace SRFI-19" moment. A couple of months back I had my nth moment with SRFI-19 and my usual partia
