Or instead of Boost.Any, create a base class for it all called like
AnimalBase that is non-templated, then your above templated Animal
class will be as it is, but subclasses from Animal, then put abstract
calls or whatever similar functionality in AnimalBase to link it all.

Variant is faster all around if you know all of your types before hand.
