Dave,

See (in the sandbox):

  boost/utility/safe_swap.hpp
  boost/utility/safe_assign.hpp

Unless there is a major bug lurking here, I think your assertion is
incorrect. (And please correct me if I'm wrong because it's very
important for boost::variant!)

If those things are supposed to have the "obvious" semantics, well, I'll
believe it when I see it.

If you don't know something extra about T it isn't in general possible
to produce a strong guarantee swap or assignment.
