Hmm... the same problem can be seen if you try

    std::make_pair("1", "2");

the template parameters are deduces as char[1] and char[1], and there's no 
much you can do with that type, not even copy it. That's the way template
argument deduction works, IIRC. I suggest that you change ctors of any and
any::holder to take value instead of reference, and tell what you got. Of 
course, you should be able to say

   boost::any test = static_cast<const char*>("Test me");
