It is highly possible that people have variables named 'declare'! To reduce the negative feeling about inventing a whole new keyword for what really is a trivial feature, can you think of new name for the keyword or a more general macro feature? Here are two possibilities: First auto typeof expr = sin(x)/x + tan(x)*exp(-3*x*x); Or #define-> how sin(x)/x + tan(x)*exp(-3*x*x) typeof(how) expr(how); 'how' available only to this line typeof(how) error(how); // error: 'how' undefined -- ---------------------------------- Siemel B.
