/**
 * @assertion Execution of an assert statement assert(e);
 * proceeds as follows:
 * The conditional expression e is evaluated to an object o. If the class of o
 * is a subtype of Function then let r be the result of invoking o with no
 * arguments. Otherwise, let r be o. It is a dynamic type error if o is not of
 * type bool or of type Function, or if r is not of type bool. If r is false,
 * we say that the assertion failed. If r is true, we say that the assertion
 * succeeded. If the assertion succeeded, execution of the assert statement is
 * complete. If the assertion failed, an AssertionError is thrown.
 * @description Checks that a compile error occurs if the conditional
 * expression e evaluates to a function that returns a Dynamic type value.
