... and both versions are easier to read if you actually include the
"and" in the LHS, sorry about that:
(define-syntax-computations and ()
(and) #f
(and x) x
(and x y z ...) (if x (and y z ...) #f))
The abbreviation could work but I think the longer version reads better.
Also the following indentation style works in this case, but in general
won't look so pretty for complex macros:
(define-syntax-computations and ()
(and) #f
(and x) x
(and x y z ...) (if x (and y z ...) #f))
