     say @b.perl;            # Array.new([1, 2, 3], 4, 5);
 
+C<[...]> creates an itemized array, and C<Array.new(...)> a non-itemized
+array.
+
 There is a slight exception though: if you call a method on an itemized
 container, it will generally behave as if it weren't itemized. So
 C<[1, 2, 3].join(',')> produces C<"1,2,3"> as a result, as one might hope.
