Are you sure that hold_any can be used with a non-streamable type at all?

Also, in assign<T>, are you sure that overwriting the old object contents 
with placement new without destroying the object first is a good idea? Looks 
like repeated a = std::string( "..." ) calls will leak the heap-allocated 
string contents on each assignment.
