     @a = ()[1,0];           # @a has no elements
     @b = (@a)[0,1];         # @b has no elements

 But:
 
     @a = (1)[1,0];          # @a has two elements
     @b = (1,undef)[1,0,2];  # @b has three elements
 
+More generally, a slice yields the empty list if it indexes only
+beyond the end of a list:

+    @a = (1)[  1,2];        # @a has no elements
+    @b = (1)[0,1,2];        # @b has three elements

 This makes it easy to write loops that terminate when a null list
 is returned:
