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)
