I have another comment more general about the any class The declaration placeholder * content; in the any class might be public or private depending on the value of the value of the define BOOST_NO_MEMBER_TEMPLATE_FRIENDS. Is it safe?

No, it's not safe. It's there for a good reason though - some compilers does not support the (required) friend declaration. Bjorn Karlsson [Non-text portions of this message have been removed]
