AFAICT the EBO support is tuned fine and on GCC it works as expected. I too was
getting a bit worse results with MSVC, but I suspect this is rather the fault of
MSVC. However, if I missed something, I'd be grateful for pointing me to the
place which is the problem.

Conditional acceptance would be OK for me and wouldn't change anything, because
I wouldn't submit the code to SVN without completing the regression tests
anyway. I decided to do this after the review, because I want to make the tests
having a stable interface (and the review is likely to change it).

Which concepts do you have in mind -- the policies or things like
CopyConstructible? The policies are described in the documentation of
constrained class template. Did I miss something there?

Thank you for your time and your vote. ;-)
