/**
 * @assertion If an unqualified identifier lexically resolves to an extension
 * method of the surrounding extension, then that identifier is not equivalent
 * to this.id, rather the invocation is equivalent to an explicit invocation of
 * that extension method on this (which we already know has a compatible type
 * for the extension): Ext<T1,…,Tn>(this).id, where Ext is the surrounding
 * extension and T1 through Tn are its type parameters, if any. The invocation
 * works whether or not the names of the extension or parameters are actually
 * accessible, it is not a syntactic rewrite.

 * @description Check that extension member resolves to an extension method of
