I think you want to add one to wanted if decl is a primary template.


OK but I am a little bit dense here: why is that necessary?

By 'primary' I mean something that is itself a template, not just amember of a class template. Previously variables couldn't be primarytemplates, but I believe your proposal is to change that; in that case,we should expect to see a template header for such a template, inaddition to any headers for enclosing classes.
