[macro] aand args ...
(mac aand args (if (no args) 't (no (cdr args)) (car args) `(let it ,(car args) (and it (aand ,@(cdr args))))))
A version of "and" where successive forms can reference previous values through "it":
arc> (aand (+ 1 4) (+ it 10))
In Scheme, scheme:and-let* (srfi-2) is the popular idiom for this purpose, though you have to provide the binding variable.
