Scott,
IMHO you raise a mighty point very much worth looking into. At least I surely will be pouring through your references, dusting off and looking at those ol' PODs (which I admit long-time discarded) from an entirely different angle.
It's also trivial for someone to build a non-POD out of the pod should they desire:
I've been thinking along these lines also. For that reasons I am leaning to resigning to the nil-generating def. cnstr as it seems the majority view and seems to considerably simplify the implementation.
Unfortunately I think any nontrivial constructor at all makes a class a non-POD. So you may have to accept the uninitialized state in order to interact well with MPI. You might consider whether you need a low-level representation class as well as a higher-level wrapper with stronger invariants. -- Dave Abrahams BoostPro Computing http://www.boostpro.com
