I know the proposals did not dig into all the corner cases -- and I don't even know whether they considered the case. But, at some point, someone has to go through the sheer number of proposals and try to paint a global picture and see how they interact with existing implementation techniques; C++ is not known to be orthogonal :-) [ in contrast, consider that the "generalized constant expressions" went through the trouble of not introducing recursion in the evaluation of constant expressions -- except the limiting cases with class templates. ] -- Gaby
