Haha... didn't think of that. Of course, if it assigns the variable to the class member function which isn't const, of course the set function can't take a const pointer since the class can modify it later.

Yes, that's my thoughts too - and I made the same mistake. I just want to have the line of the error clarified.

It was on the definition line.

So would this be one of the cases where you'd want to return a const pointer instead of a pointer to a const object?

Edit: Errr... I meant 'accept', not 'return'.

No, the setNext musn't take a pointer to const (const T*), because you can't demote to non-const w/o a cast (a bad cast).
You can take a const pointer (T* const), sure, but it doesn't really help.
