// 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.
