[Voted into the WP at the March, 2011 meeting as part of paper N3262.]
The ellipsis for a parameter pack enters the normal declarator grammar as part of the declarator-id nonterminal. In contrast, however, the abstract-declarator grammar has no counterpart to declarator-id; instead, the ellipsis is one of the productions for the abstract-declarator nonterminal itself. It is thus impossible to declare a parameter pack for a pointer or reference using an abstract declarator, e.g.,
template<typename... T> void f(T& ...t); // t is a parameter pack template<typename... T> void f(T& ...); // equivalent to void f(T&, ...)
