I'm trying to specialize boost::lexical_cast to convert Objective-C 
objects into various standard C++ classes (for example, leveraging 
NSNumber::-intValue to create lexical_cast<int>(NSNumber*)).  However, 
as Objective-C objects exist as pointers, I would imagine that they 
would fail the requirements of needing well-defined streaming 
operator<<() in order to use the stock boost::lexical_cast.  Any words 
of advice on how to do this in a way that will do as little damage as 
possible?
