+// C++98 [basic.lookup.classref]p1:
+// In a class member access expression (5.2.5), if the . or -> token is
+// immediately followed by an identifier followed by a <, the identifier must
+// be looked up to determine whether the < is the beginning of a template
+// argument list (14.2) or a less-than operator. The identifier is first
+// looked up in the class of the object expression. If the identifier is not
+// found, it is then looked up in the context of the entire postfix-expression
+// and shall name a class or function template. If the lookup in the class of
+// the object expression finds a template, the name is also looked up in the
+// context of the entire postfix-expression and
+// -- if the name is not found, the name found in the class of the object
+// expression is used, otherwise
+// -- if the name is found in the context of the entire postfix-expression
+// and does not name a class template, the name found in the class of the
+// object expression is used, otherwise
+// -- if the name found is a class template, it must refer to the same
+// entity as the one found in the class of the object expression,
+// otherwise the program is ill-formed.
