Provided by: kaya_0.4.4-6ubuntu3_amd64 bug

NAME
       Array::filter - Filter a list according to a predicate.


SYNOPSIS
       [a] filter( Bool(a) p, [a] xs )


ARGUMENTS
       p The predicate to test against

       xs The array to filter


DESCRIPTION
       Each element of xs is tested against the predicate p

       The  returned  list contains those elements of xs for which the predicate is true. The predicate function
       may of course be partially applied for ease of programming.

    Bool isDiv(Int d,Int a) {
        return (a%d==0);
    }

    Void main() {
        ints = [1,2,3,4,5,6,7,8];
        odds = filter(isDiv@(3),ints);
        // odds = [3,6];
    }

       Naturally, all(p,filter(p,xs)) == any(p,xs)
