1 -- The following two hints warn to simplify e.g. "map (\v -> (v,
2 -- True)) lst" to "zip lst (repeat True)", which is more abstract
3 warn = map (\v -> (v, x)) y ==> zip y (repeat x)
5 warn = map (\v -> (x, v)) ==> zip (repeat x)
8 -- The following warn on use of length instead of null
9 warn = length x > 0 ==> not (null x)
10 warn = length x /= 0 ==> not (null x)
11 warn = length x == 0 ==> null x
