Attached is the patch for the items that Eli identified earlier
(improvements in comments and breaking one long line). I'll wait for any
further changes/comments. Then I think its best to squash this down to 2
commits: one for the GC marking, and all the rest related to
sorting. (I'm happy to use more commits if you think the predicate
resolution or the unit tests deserve their own patches).

Best,
Andy
