Why is `boost::any` better than `void*`?

Question

What inherent advantages do boost::any and boost::any_cast offer over using void* and dynamic_cast?

Answer 1

This is what boost's reference says:

It supports copying of any value type and safe checked extraction of that value strictly against its type.

Neither of those can be done with a void*. There are no checks for you and you have to know yourself what you can cast it to.

I don't think dynamic_cast enters the picture at all, as it hasn't directly anything to do with either.
