Currently, Boost.Utility is something of a mixed bag and consequently, a 
dependency knot. Nearly everything in Boost depends on Utility via (say) 
boost/assert.hpp, while at the same time Utility itself depends on much of 
Boost via Iterator (and others). Something Must Be Done.

At minimum, assert.hpp, current_function.hpp, ref.hpp, checked_delete.hpp 
and addressof.hpp need to be moved out. I suspect that call_traits.hpp, 
compressed_pair.hpp, enable_if.hpp also don't belong.

assert.hpp and current_function.hpp should probably go into their own 
library, Boost.Assert. ref.hpp might go to Boost.Bind. checked_delete.hpp 
might perhaps go to SmartPtr. No idea where addressof.hpp needs to go.

These are just suggestions. I'm open to any resolution, as long as the 
dependency (and, to a lesser extent, maintenance) problem is resolved to 
everyone's satisfaction.
