splice ARRAY
Removes the elements designated by OFFSET and
LENGTH from an array, and replaces them with the
elements of LIST, if any. In list context,
returns the elements removed from the array. In
scalar context, returns the last element removed,
or "undef" if no elements are removed. The array
grows or shrinks as necessary. If OFFSET is
negative then it starts that far from the end of
the array. If LENGTH is omitted, removes
everything from OFFSET onward. If LENGTH is
negative, leaves that many elements off the end of
the array. If both OFFSET and LENGTH are omitted,
removes everything.
