 * @assertion Evaluation of a getter invocation i of the form e.m proceeds as follows:
 * First, the expression e is evaluated to an object o. Then, the getter function
 * m is looked up in o with respect to the current library, and its body is
 * executed with this bound to o. The value of the getter invocation expression is
 * the result returned by the call to the getter function.
 * @description Checks that a getter body is executed with [:this:] bound to o.
