[Voted into the WP at the March, 2011 meeting as part of paper N3262.]
According to 13.2 [temp.param] paragraph 11,
If a template-parameter of a class template has a default template-argument, each subsequent template-parameter shall either have a default template-argument supplied or be a template parameter pack. If a template-parameter of a primary class template is a template parameter pack, it shall be the last template-parameter. [Note: These are not requirements for function templates or class template partial specializations because template arguments can be deduced (13.10.3 [temp.deduct])...
Should the Standard forbid non-final parameter packs in cases where the declaration does not allow the template arguments to be deduced? For example,
template<typename... T, typename... U> void f() { }
template<typename... T, typename U> void g() { }
