map does not accept no list:

guile> (map (lambda (a) a))

In standard input:
   1: 0* [map #<procedure #f (a)>]

standard input:1:1: In procedure map in expression (map (lambda # a)):
standard input:1:1: Wrong number of arguments to #<primitive-generic map>
ABORT: (wrong-number-of-args)

+ and * have a "natural" identity (0 and 1), so it is not silly that (+ a) is
(+ a 0) and (+) is (+ 0 0), but #t does not strike me as a natural identity
for < -- (< 1 1) is #f.   But I hate these kinds of discussions, so I defer...
