The image is one started from "Squeak4.3alpha-11481" and updated by
pressing the "update code from server" button.  The result of
#symbolic is like this:

37 <71> pushConstant: true
38 <AC 0F> jumpFalse: 55
40 <70> self
41 <21> pushConstant: #anything
42 <E0> send: apply:
43 <68> popIntoTemp: 0
44 <70> self
45 <22> pushConstant: #spaces
46 <E0> send: apply:
47 <87> pop
48 <70> self
49 <24> pushConstant: #seq
50 <10> pushTemp: 0
51 <8A 81> pop 1 into (Array new: 1)
53 <F3> send: apply:withArgs:
54 <90> jumpTo: 56
55 <73> pushConstant: nil
56 <7C> returnTop
