This is going to be re-purposed into a more general bugreport about constexpr
and diagnostics. The goal is to try and get compiler messages about why code
constructs are or are not valid constant expressions that contain:

1) locality as to where the problem is

2) clarity as to what the problem is

3) notes as to potential fixes.

Now, on to the attachments.
