Re: [boost] [pimpl] Mini Review

Hi, I just wanted to add an example... I think Pimpl should have the following property: a) struct X { int f(); private: int a_; }; b) struct X : public pimpl<X>::value_semantics { int f(); }; The user of class X should not be able to tell the difference between a) and b). X x; Now in this case the user can tell the difference. In b) he can do x.null(), but in a) he can't. So Pimpl changes the interface. And that's what I want to avoid. Pimpl or no Pimpl, the interface of X should stay the same. Regards Kris
