Many thanks for your crash-course on aggregates and your patence with me. Much and truly appreciated. I had to dig the Standard up for a "refreshment". It's embarassing but I admit I all forgot about that "C" stuff tucked away in a corner of C++. I never thought I'd come across it ever again.
Kudos to you for your effort. I am coming to appreciate your implementation. It's very impressive how efficiently you managed to cut off "all the excess" and how far you've got without C++ "perks and whistles". I am sure it had its uses. That said, I feel aggregates' limitations are far too restrictive for a full-fledged implementation (and especially the interface).
