Any Haskellers here? How would you rewrite the following function in Guile?
foo :: [Int] -> String -> [Int] foo (x:y:ys) "+" = (x + y):ys foo (x:y:ys) "-" = (x - y):ys foo xs num = read num:xs *Main> foo [] "42" [42] *Main> foo [1,2] "42" [42,1,2] *Main> foo [1,2] "+" [3] *Main> foo [1..10] "42" [42,1,2,3,4,5,6,7,8,9,10] *Main> foo [1..10] "+" [3,3,4,5,6,7,8,9,10] It will fail if you call it like this: *Main> foo [] "+" [*** Exception: Prelude.read: no parse But let's assume that it's OK. I guess that 'match' is the answer, but I don't understand how to use it.
