The issue there is that the initializer_list wasn't static, but here it is, so
the array temporary should be as well. And presumably the problem is that we
aren't representing that lifetime extension in a template. And checking the
initializer gives up on trying to enforce that. But then when we try to
evaluate the template argument we find that we don't have a constant value to
work with, and complain.
Instead, we should probably treat num as value-dependent even though it
actually isn't. Or fix it to be properly evaluated by representing the
lifetime extension somehow.
