In DTL, Paul Harris actually just created a version of boost::optional to 
handle NULL values which worked very well as a way to read and write types 
that could be null.  He also did mappings of the boost::posix_time class and 
we also used a version of the boost:variant class to provide dynamically 
bound types (where you don't know the types until runtime).
