Opps, my fault using ->*
it should have been:
(define/contract (test1 . xs)
 (->* () () #:rest (listof number?) void?)
 (display xs))

I guess the case-lambda-procedure kind of error message made me think
it was a bug. :-/

(Interestingly enough, the thought of a bug was reinforced as this
error first occurred when I tried the new version but as it happens I
had never exercised some of my lib functions before. :) )
