/**
 * @assertion Evaluation of a getter invocation i of the form C.m proceeds as follows:
 * If there is no class C in the enclosing lexical scope of i, or if C does not
 * declare, implicitly or explicitly, a getter named m, then a NoSuchMethodError
 * is thrown.
 * Otherwise, the getter function C.m is invoked. The value of i is the result returned by
 * the call to the getter function.
 * It is a static warning if there is no class C in the enclosing lexical scope
 * of i, or if C does not declare, implicitly or explicitly, a getter named m. The
 * static type of i is the declared return type of C.m if it exists or dynamic otherwise.
 * @description Checks that the value of a getter invocation of the form C.m is the value
 * returned by the appropriate getter function in C.
