Actually, if you look at boost::any (which can easily be cloned), C++ is
easily capable of storing data of ANY type, be it char or short or
structs or ints or whatever. The only drawbacks I see are speed (but,
probably not enough to be serious) and type-safety, which is actually
what we not want. Oh and it requires RTTI.

By the way: I already wrote an extended version of boost::any which I
could give away, if MPL/GPL/LGPL-triple is not what you want, we could
talk about other licenses. My version eliminates some drawbacks of
boost::any - but it's not yet finished. And it might be too complex. In
that case, writing a trivial clone of boost::any is a matter of 30
minutes.

If you don't like RTTI, it's possible to write an unsafe version which
does not use RTTI. I would not recommend this.
