--- Comment #4 from Benjamin Kosnik <bkoz at gcc dot gnu.org> 2010-11-03 17:32:23 UTC --- 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.
