Excellent point! And as long as we have them I agree with Alan that the boolean data type should implement real boolean algebra with respect to +, *, and ~, for example supporting operator precedence appropriately (versus using and, or, not) and also correctly implementing DeMorgan's laws and other property's of boolean algebra ~(a*b) == ~a + ~b etcetera. 1+True is bad practice and should be an error. Anything else is false advertising (and the java community has the patent on that methodology :c) ). -- Aaron Watters === Why does a giraffe have such a long neck?
