+// 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.
