I'd be inclined to go the other way: create variant_cast, but also supply a
boost::any overload of variant_cast that is a thin wrapper around any_cast.
The reason is one of pure naming: a variant doesn't take 'any' type, it takes
any of a set of types, whereas boost::any is a variant type (an unbounded
one) as is the variant we're discussing. Basically, I think 'variant_cast' is
a better name for all variant types whereas 'any_cast' is only suitable for
