External callable is good and is that easy. But is lisp good for library construction and for other system to use. Many languages are not in this niche (is swift or apple os easily callable if not using objective c), but Common Lisp gives an impression it is more like it to be the centre, if not hotel California like. In fact one key feature or bug is it’s dynamic nature - debugging, typing, object and method etc - might be lost. In this regards callable from outside and unlike c which is not built for others (as os is to be called) one wonder what is to be gained. Obviously it could be one of the foundation of a large system. But can the satellite be others is my question. Can I have CL core and say python front end etc.
