I am wondering whether you are intellectually honest enough to state the weaknesses as well as the strengths of the Lisp approach. For example, in the world of physical engineering, we must acknowledge that steel is endowed with greater tensile strength than concrete, whereas concrete is characterized by greater compression strength. This knowledge leads to designs that combine the corresponding strengths of both concrete and steel in the creation of reinforced concrete beams. There are, admittedly, many benefits from the Lisp dynamic typing model, under some circumstances. There are many disadvantages, under other circumstances, to the static typing model of Ada, C++, and others. Since Ada is more type safe than those others, those disadvantages sometimes are more pronounced. However, there are definite benefits to the static typing model, when it is used intelligently, and those often outweigh the disadvantages. Where do you see the disadvantages of the Lisp dynamic typing approach? Richard Riehle
