Quote from: "Lutz"I have a new page on http://newlisp.org/index.cgi?FAQ">http://newlisp.org/index.cgi?FAQ , (not integrated yet into the menu) It talks also about the philosophical differences between Common Lisp and newLISP in the second paragraph:  "Why newLISP, why not one of the other standard LISPs ?" .

VII.

'nil' and 'true' are boolean constants in newLISP. In Common Lisp and

Scheme they have an additional role as list terminator:



 ;; Common Lisp and Scheme

 (cons 'x nil) => (x)



 ;; newLISP

 (cons 'x nil) => (x nil)

Not true for Scheme:

       nil



1> (cons 'x '())

'(x)



Scheme has separate notation for false (#f -- false, #t -- true),

and end of list '().

X.

newLISP has only one operator for equality, the equal sign = in other

LISPs you may have 4, equal, eql, eq =, for expressions, symbols or

numbers, symbols and numbers.

Common Lisp has more than 4:



eq, eql, equal, equalp, =, string=, string-equal, char=, char-equal.
