/* ??? Can we actually assume that, if template_id ==
error_mark_node, we will have issued a diagnostic to the
user, as opposed to simply marking the tentative parse as
failed? */
if (cp_parser_error_occurred (parser) && template_id !=
error_mark_node)
=> error_at (token->location, "parse error in template argument list");
But actually the issue is that template_id != error_mark_node, but it is not a
template id, so we are still tentatively parsing and this error is wrong.
