The right way to think about temporary code is that if it's supposed to be quick to address, you don't want to introduce a temporary way of proceeding that will change later as the change will annoy some users. And if the reason for the temporary step is a temporary difficulty, you can be certain nobody will ever try to address it and that temporary will be definitive. So thinking "temporary" should generally ring a bell "am I going to annoy users for no reason or am I putting myself in a wrong corner". That's why I really try to avoid anything "temporary". (But there's no problem with making the wrong choice and regretting later, of course ;-)). Cheers, Willy
