[offending snippet below.  I can make the full running source available no
problem, but it can't be pasted in this window.  Instead contact
address@hidden


(define (perform target :: Steppable      ;;;;; THIS IS LINE 275.  Problem
occurs regardless of function name
            method :: symbol
            #!key
            (at :: <double> (floor (+ 1.0 (schedule:getTime))))
            (order :: <int> 0.0) 
            (repeat 1.0))
  (let ((agent (referring-agent target method)))
    (if (eq? #f repeat)
        (schedule:scheduleOnce at order agent)
        (schedule:scheduleRepeating at order agent repeat))))
