Exactly!  This is what I love so much about this language!  It has so many benefits, from security to software reliability to correctness of execution.  This is such a powerful portion of the language that nothing else quite compares.

I covered this topic in two chapters.  One dealt with the primitives that are already baked in the language and the second one dealt with the custom types that you mention.
