1. You might way to include a general treatment of placeholder symbols (_1, _2, _3, ...) in you're library, to help reduce the number of different conflicting definitions from various libraries. I use placeholder symbols (_1, _2, _3, ...) as public static members of lazy::type<T>. So there shouln't be such problems.
What do you think which statement is more readable and understandable? LAZY_ALIAS(-Matrix_ + Matrix_ = Matrix_._2 - Matrix_._1); or LAZY_ALIAS(-Matrix_ + Matrix_ = _2 - _1); If second then I better include such support.
2. You might provide native support for reference wrappers, from Boost.Ref (or TR1).
Matrix a, b, c, d, e; //.. a = (b + c * d * (d + -b + - - c); Expression template on rhs operators only with references to a, b, c, d, e. Also I use boost::call_traits<T>::param_type where building expession template. So I think there is no need for such support. Maybe I misunderstand something? -- Pavel Chikulaev
