 | 	C++ allows the word 'typename' after a 'using' directive.  _The C++ Programming Language_ (third edition) [Stroustrup], section A.7 (Grammar/Declarations) defines the using directive:
 | 	  using-declaration:
 | 	      "using" "typename"(opt) "::"(opt) nested-name-specifier 
 | 	      unqualified-id ";"
 
 The C++ grammar is not context-free, you cannot deduce construct
 validity just from pure grammar productions.
