There is a trade-off. Making the changes to the
"any.hpp" header will allow you to stream your
classes. But it also constrains the types that can be
placed within the "any" class. After the changes, you
can only place those types that have operator<<
defined into the "any" class.

That is why you should perhaps rename your modified
"any" class to avoid confusion with the original
class.
