Of course I'm serious.  Remember, indices aren't keys.  They're just
positions.  splice completely removes an entry from an array in a way 
that undef will not, just as delete completely removes an entry from a
hash the way that undef will not.

Now, could someone please tell me what to fill in for XXXXX?
