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
