  Returns a MutableVector containing the values of the current MutableVector starting after and including the first value that produces true when passed to the specified callback
• ->slice(int $start, int $len): MutableVector<Tv>
  Returns a subset of the current MutableVector starting from a given key up to, but not including, the element at the provided length from the starting key
