In this exercise I'm using Visual Studio 2019 and a modified version of the std_lib_facilities header found here.
Chapter 25 // Exercise 17
In section 25.4.3-4 we provided a class Array_ref claimed to make access to elements of an array simpler and safer. In particular, we claimed to handle inheritance correctly. Try a variety of ways to get a Rectangle* into a vector<Circle*> using an Array_ref<Shape*> but no casts or other operations involving undefined behaviour. This ought to be impossible.

Wow it's been a hot minute since I last looked at the FLTK code. I would avoid using arrays entirely but this little class is handy. There's no code for this one as none of it compiles anyway.
And with that I'm onto the second to last chapter of the book...it feels strange. What will I do without the exercises in this book hanging over my head?
