{
    return enum_grep0(obj, pat, Qfalse);
}

Inverted version of Enumerable#grep. Returns an array of every element in enum for which not Pattern === element.

Example

(1..10).grep_v 2..5   #=> [1, 6, 7, 8, 9, 10]
res =(1..10).grep_v(2..5) { |v| v * 2 }
res                    #=> [2, 12, 14, 16, 18, 20]
