Just to clarify, if it was not clear enough in my original message, the  
*intent of this thread* is not to change the existing behaviour of  
optional, or argue for a change, rather, it is to understand the  
implications of a change, since I assume there are people on this forum  
that are more knowledgeable than me with respect to the usage of  
Boost.Optional.

As for your latter remarks, I would have to strongly disagree with that,  
and I'll just leave it at that, since my motivation for exploring the  
implications of the said change to optional is tangential to the intent of  
this thread.
