splice is a special form of the ? verb which takes 3 arguments.

  • x is the array to be modified.
  • (s;e) is a two element array indicating start index and end index
  • z is the replacement array.

In ngn/k, splice removes the portion of the array x from s to e, exclusive of e and inserts z in that place.
