I had no idea the concept of an atom had indeed degenerated all the way into complex numbers, which to me and to all decent Americans will always be a "cons" cell. Obviously I had not reckoned with the full and complete degeneracy of Clozure Common Lisp Version 1.10. Or something. If I knew Lisp, I could perhaps condemn it correctly.
In any case, sir: you are misinformed. A "dynamic" type system isn't actually a type system. At best, it's a sort of crutch for retired Jedis who can barely swing their obsolete, one-ended lightsabers.
Or do you wish to become enlightened? Come visit our library, old Jedi. At urbit.org, we have all the enlightenment you need. The age of Lisp was glorious, true. But much time has passed and much we have learned. The times change, uncle, and we must change with them.
