Yeah, and I agree with the outcome of that discussion - which was about
finding a type with nothrow default constructors, not about singular
variants. This is not the ideal solution - that would take something like a
policy. The point is that those who want variants that can be singular can
get them - albeit through a less than ideal syntax.
We have two choices:
(1) People who need variants that can be singular can get them but they have
to use the unusual and possibly confusing syntax of putting boost::empty as
the first type.
(2) All variants can be singular.
Do you agree with that?
Brock
