I'd suggest making variant part of mpl. With that, the problem disappears. Yes, variant, mpl, tuple (or fusion), should play well together. A good first step would be to start using the same type to mark that no type was specified (instead of the variations void_, null_t, ...). FYI, variant is now a valid fusion sequence.
I don't get it. What are the values of the non-stored elements?
Default constructed *only* when dereferenced. Iteration only does not touch the data. Regards, -- Joel de Guzman http://www.boost-consulting.com http://spirit.sf.net
