puzzling things

[Andy Wingo]

Hey gang,

Why doesn't the following code work?

(define second-arg
  (procedure->syntax
   (lambda (x y) (cadr x))))

((lambda () (second-arg a b c d)))

I get some kind of error like this:

  18: 2* [cadr (address@hidden a b c d)]
 
<unnamed port>:18:18: In procedure cadr in expression (cadr x):
<unnamed port>:18:18: Wrong type argument in position 1: (address@hidden a b c 
d)

What's that all about? I poked around in the source but got lost in a
bunch of ilocs and glocs. What's an iloc anyway? Well. The first
question is the important one. Any insights?

regards,

wingo.
