/**
 * @assertion For any member access, x.foo, x.bar(), x.baz = 42, x(42), x[0] = 1
 * or x + y, including null-aware and cascade accesses which effectively desugar
 * to one of those direct accesses, and including implicit member accesses on
 * this, the language first checks whether the static type of x has a member
 * with the same base name as the operation. That is, if it has a corresponding
 * instance member, respectively, a foo method or getter or a foo= setter, a bar
 * member or bar= setter, a baz member or baz= setter, a call method, a
 * []= operator or a + operator. If so, then the operation is unaffected by
 * extensions. This check does not care whether the invocation is otherwise
 * correct, based on number or type of the arguments, it only checks whether
 * there is a member at all.
 *
 * @description Check that dynamic invocation doesn't invoke any extension
 * method
