Re: [DOC] About Lisp Data Types

[Kevin Vigouroux]

I agree with you. 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’s 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.

• An expression is a Lisp object which gives its meaning.
• An expression cannot be understood in its original form (text).

It makes no sense at first.
