Collection implements a printing protocol to avoid stack overflows, but it is inadequate.
The following example is paraphrased from something I just encountered. (I didn't make the example up, just for the sake of reporting an error! <s>)

a := Array new: 1.
a at: 1 put: 'second' -> a.
a printString
The recursion set logic doesn't really help if the self-reference occurs inside one of the elements.
