I think the old Lisp tradition of using lists for everything is related to this somehow. On the other hand, in Common Lisp programmers can define custom types that have to fulfill a predicate function. Then, if they declare the types of their functions, most implementations will generate type-checking code unless instructed not to. So in Common Lisp you can use lists for everything but still have type-checking, at some cost to efficiency. :D |
