[I assume you refer to p8 and the sentence: "If an argument is a pack expansion
(14.5.3), it shall be the last argument in the template argument list."]
No. list_templates<F...> is not an argument that *is* a pack expansion (but it
contains a pack expansion, which is fine). This sentence describes a situation
like the following:
template<class>
struct P;
template<class...>
struct X;
template<class... Ts, class T>
struct X<Ts..., P<T>> {};
This is ill-formed because the expansion Ts... is not at the end of the
argument list.
Changing it to
template<class... Ts, class T>
struct X<P<T>, Ts...> {};
would be OK, though.
