+    .note = at compile-time, pointers do not have an integer value
+    .note2 = avoiding this restriction via `transmute`, `union`, or raw pointers leads to compile-time undefined behavior

+    .teach_note =
+        The value of statics and constants must be known at compile time, and they live for the entire lifetime of a program. Creating a boxed value allocates memory on the heap at runtime, and therefore cannot be done at compile time.

+    .teach_note =
+        A constant containing interior mutable data behind a reference can allow you to modify that data.
+        This would make multiple uses of a constant to be able to see different values and allow circumventing
