The proposal is:

- move the polymorphic casts into their own header, in conversion, 
boost/polymorphic_cast.hpp;
- move boost/cast.hpp, which is now

#include <boost/implicit_cast.hpp>
#include <boost/polymorphic_cast.hpp>
#include <boost/numeric/conversion/cast.hpp>

into numeric/conversion, pending deprecation.

Everyone seems to agree on that, so what do you need to move forward with 
it? Will just an empty 'lexical_cast' repository be enough, or do you need 
me to do something else? Perhaps cloning the current contents of 
'conversion' into 'lexical_cast' may be a better starting point?
