Very nice!

A few comments:
- What's y?
  void swap(flyweight& x)

  {

          std::swap(x.h,y.h);

  }

- I'm not convinced operator< should be in terms of the pointer.  x<y
being different from (T&)x < (T&)y seems like an easy source of
errors.

<OT> Has anyone proposed a good way of doing wrapping for C++0x?  That
problem keeps coming up...
