Not a bug, but inefficiency. Method Link>>at: for negative indexes scans
the entire list. My solution is:

  at: index [
     |i|
     index<1 ifFalse: [
        i := 1.
        self do: [:element| i=index ifTrue: [ ^element ]. i:=i+1 ]
     ].
     SystemExceptions.IndexOutOfRange signalOn: self withIndex: index
  ]
