Hmmh, I cannot relate LWG issue 301 to this point of question or even
Howard Hinnant related to this ;-)

Maybe you mean your **own** issue 227


But I see no connection to my point, which is obviously related to
my missing definition of Swappable. This terminus cannot be found
in C++98, nor could I find any definition on the pages of the commitee.

OK, I mean by swappable that this type provides a swap member function.

I do not see any connection between swapable and copyable. You could
even allow a swap for any (dynamic) std::container w/o copyability.

This is related to the swapability of boost::scoped_ptr which also does not
provide copy-semantic, but fulfils swapability.
