/// @assertion A static variable is a variable that is not associated with
/// a particular instance, but rather with an entire library or class. Static
/// variables include library variables and class variables. Class variables
/// are variables whose declaration is immediately nested inside a class
/// declaration and includes the modifer static.
/// A library variable is implicitly static. It is a compile-time error to
/// preface a top-level variable declaration with the built-in identier static.
/// @description Checks that a static variable is not associated with a
