From: Gabriel Dos Reis <Gabriel.Dos-Reis@cmla.ens-cachan.fr> To: sethml@ofb.net Cc: gcc-gnats@gcc.gnu.org, debian-gcc@lists.debian.org Subject: Re: c++/3033: 'using typename' construct doesn't work Date: 02 Jun 2001 02:58:27 +0200 sethml@ofb.net writes: | 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. -- Gaby
