Boost.Optional seems to really have a lot of potential for what I want to  
do, but one thing about it has been nagging me, specifically it's  
assignment semantics for wrapped references being different from the  
semantics of bare C++ references (see http://tinyurl.com/4yna643).

Has/have the author(s) of the library or anyone considered disallowing  
assignment for Boost.Optional types that wrap references, and if so, what  
would the consequences of this entail?  I rather disallow assignment in  
this case, then have what's basically a wrapper class behave partially  
differently than the type it's supposed to emulate.

Thanks in advance,

Mostafa
