I agree that it's not a good term. Also, you're confusing your posters - "abstraction now leaks" was introduced by someone opposing the optimization (dymk), not the OP (londons_explore, who used "insufficient abstraction"). And when I used it I intentionally paraquoted as "claimed abstraction leakage", due to the leaky terminology.
