--- Comment #1 from Jonathan Wakely <redi at gcc dot gnu.org> ---
The ideal would be a fix-it hint suggesting to add the comma.
Adding the '>' that the parser says is expected would not make the code correct
because 'template<typename T> typename U>' isn't valid as a top-level
declaration (only as a template-parameter).
