I think the change in constant_value_1 is better. We should try to
preserve the value-initialization vs. direct-initialization distinction
until the point of instantiation; even though it doesn't matter for
scalars, it does matter in general, and it's tidier not to mess it up.
So, the constant_value_1 change is OK.
