I can't understand anyone considering processing instructions an ugly wart because they don't get in the way of anything you want to do, the only way they could ever cause grief is if you need to work with them, in which case, well, duh, you need to work with them it seems, the implication of needing to work with something being that you need that something. I hardly ever use pi's, generally finding that some other solution is better, but just because I hardly ever use something doesn't mean I can't see the need for it. |
