hello all,
One little question: is it possible to make a class assignable which has reference type members?
Hello Max,
yes it is possible. Just assign the reference member of the rhs to the the reference member of the lhs.
The single feature of references is that they are no default constructible. Maybe your question was? is it possible to make a class which has reference type members default constructible?

I think he wanted the references to be copied the way pointers would be; i.e after A = B, A refers to the same objects B does (not a copy). I dont think you can change reference to refer to another object once it is initialized (sec 8.5.3 par. 2). I wonder if you can use placement new and make the assignment operator for your class invoke a copy constructor? -- John
