Don't get me wrong; I don't mean to say it's not fantastic, just that the headline was misleading. My expectations for "Hey, we managed to move this stuff to compile time" is that it will be 1) more interesting theoretically, and 2) less interesting practically (at least in the short term). Either can be fantastic, and these expectations are sometimes violated besides, but I just wanted to give a heads up to others (at least, those that skim the HN comments first) or be corrected if my reading of it was wrong.
