[boost] [utility] nonconstructible

Hi,
I think it would be nice to have a "nonconstructible" class to derive
from similar to noncopyable.

Recently I was burned by a traits class that was getting constructed.
I think this should also be used for template metafunctions.

I envision something like the following:

struct nonconstructible
{
  private:
   nonconstructible() {}
}

template<typename T>
struct my_traits : nonconstructible
{
  typedef int my_type;
};
