> ~20 years. Common Lisp was designed for interpretation and compilation from day one. The first implementations from 1984/85 had already compilers. > Common Lisp, for example, is probably more dynamic than Python Some parts are more dynamic than Python, some not. For example everything that uses CLOS+MOP is probably more dynamic. Also some stuff one can do when using a Lisp interpreter may be more dynamic. CL is more static, where one uses non-extensible functions, type declarations, static compilation, inlining, ... The parts where a CL compiler achieves good runtime speed may not be very 'dynamic' anymore.
