@shafik I think you're right based on the current standard wording, but that
this is a bug in the wording of the standard. The situation described in
[expr.const]/28.5's example is a fallback from constant evaluation of the
initializer to runtime evaluation, and that fallback shouldn't be possible for
a static const data member. Will ask CWG.
