I've got some nice idea from discussion: nullable variant. If many people use or want to use a variant with a type, that represents empty state, we can create a separate nullable variant class. I think that nullable variant can be implemented more efficient that the current variant. For example we can simplify copy/move constructors and assignment operators, guarantee fast noexcept default construction, simplify metaprogamming and reduce compilation times. Maybe someone want to implement it?
I like it! If you implement it, I'll be your first user :-) I don't really care much about this "never empty" guarantee and I think it's not really worth the trouble.
How is this different from variant< blank, ... > ? - Jeff
