Unfortunately, some parts of the explanation are unclear or missing. In other languages, an expression is text; it has no other form. In Lisp, an expression is primarily a Lisp object and only secondarily the text that is the object=E2=80=99s read syntax. Often there is no need = to emphasize this distinction, but you must keep it in the back of your mind, or you will occasionally be very confused. =E2=80=A2 An expression is a Lisp object which gives its meaning. =E2=80=A2 An expression cannot be understood in its original form (text). It makes no sense at first. --=20 Best regards, Kevin Vigouroux
