+// [class.mfct.non-static]p3:
+//   When an id-expression (5.1) that is not part of a class member
+//   access syntax (5.2.5) and not used to form a pointer to member
+//   (5.3.1) is used in the body of a non-static member function of
+//   class X, if name lookup (3.4.1) resolves the name in the
+//   id-expression to a non-static non-type member of some class C,
+//   the id-expression is transformed into a class member access
+//   expression (5.2.5) using (*this) (9.3.2) as the
+//   postfix-expression to the left of the . operator. [ Note: if C is
+//   not X or a base class of X, the class member access expression is
+//   ill-formed. --end note] Similarly during name lookup, when an
+//   unqualified-id (5.1) used in the definition of a member function
+//   for class X resolves to a static member, an enumerator or a
+//   nested type of class X or of a base class of X, the
+//   unqualified-id is transformed into a qualified-id (5.1) in which
+//   the nested-name-specifier names the class of the member function.
