My point was that making generalizations about Lisp is like making generalizations about languages with C-like (perhaps more correct ALGOL-like) syntax.  Most people wouldn&#x27;t make a statement about Java and assert that it applied to C++, too.  This is why saying that Lisp has no type system doesn&#x27;t make much sense.  There are many <i>completely different</i> languages that use s-expression notation, and they all have different feature sets, much like all the C-like languages.
