+
+Creating a reference is done with an ampersand. It creates a pointer to another variable in the stack, which could be a pointer to something on the heap.
+
+This is called borrowing.
+
+A reference is a non-owning pointer; so if we create a reference to a Box we can safely have it discarded and continue using the box because the heap data is not deallocated.
