/**
 * @assertion The formal parameter list of a function introduces a new scope 
 * known as the function's formal parameter scope. The formal parameter scope 
 * of a function f is enclosed in the scope where f is declared.
 * Every formal parameter introduces a local variable into the formal parameter scope.
 * However, the scope of a function's signature is the function's enclosing scope,
 * not the formal parameter scope.
 * The body of a function introduces a new scope known as the function's body
 * scope. The body scope of a function f is enclosed in the scope introduced by
 * the formal parameter scope of f.
 * @description Checks that the function scopes are enclosed in the scope where it's
 * declared and not the one where it's invoked.
