Hello,

You might want to give a glimpse at this previous thread :
"[boost] [property] interest in C# like properties for C++?".
1/ you will see an interesting use of the defect 45 (<=> subclasses can access private members of parent class). More traditionnally, a friend might also have been used.
2/ no 'directly' stored pointer (recalculated at each access).
3/ lots of discussions on the subject.
