I have a macro which defines constants as powers of two (for
interfacing with xlib):

(defmacro define-bitmask-constants (&rest name-power-pairs)
  "Define a list of constants from name-value pairs, raising 2 to
the power value."
  (labels ((dbc (pairs)
	     (case (length pairs)
	       (0 nil)
	       (1 (error "no power after ~a" (car name-power-pairs)))
	       (t (destructuring-bind (name power &rest rest) pairs
		    `((defconstant ,name (expt 2 ,power))
		       ,@(dbc rest)))))))
    `(progn
       ,@(dbc name-power-pairs))))

But when I apply it, the first argument is indented too much.  For
example,

(define-bitmask-constants 
    USPosition 0
  USSize 1
  PPosition 2
  PSize 3
  PMinSize 4
  PMaxSize 5
  PResizeInc 6
  PAspect 7
  PBaseSize 8
  PWinGravity 9)

Any suggestions?  This is cosmetic, but I would be interested to know
why this occurs.

Thanks,

Tamas

Ah, where are the powers of 2 again?

I think replacing &rest with &body would make it.
