All solutions require knowing all of the types that storage must be aligned
with in advance. It works quite well for, e.g., a bounded variant class (such
as those written by Brian Parker and Andrei Alexandrescu), but any unbounded
variant (such as boost::any or boost::function) won't benefit because they
don't haven't anything to align with.
