* @assertion For the purposes of extension method resolution, there is no
* special treatment of nullable types with respect to what members are
* considered accessible. That is, the only members of a nullable type that are
* considered accessible (and hence which take precedence over extensions) are
* the members on Object.
* @description Check that extension method resolution is applicable to the
* nullable type. Test type alias for A?
