Good point! Thanks for clearing that up for me. > Interestingly, I don't _think_ you can cause an object to get pruned > accidentally here, because: [snip] I appreciate the additional context that you gave (and I snipped). This makes me comfortable accepting this test as an exercise of the code (to guard against future changes that create failures like null-refs) and we will need to rely on the performance suite to catch issues like removing the SEEN markers that I had tested.
