+ * subject to change during run time.
+ *
+ * Please note that the problem with global variables is that anyone can change
+ * them whenever. This makes it extremely hard to reason about your code. But
+ * for constants, this is not a problem since we cannot change them, and
+ * therefore they stay the same during the entire execution of the program.
