--- Comment #2 from Paolo Carlini <paolo.carlini at oracle dot com> 2011-05-30 09:20:30 UTC --- Thanks Daniel. Depending on how this issue is resolved - at this point I'm pretty sure it's an actual issue - given also the inconsistency vs the static_assert, I will actually use something similar in the library.
