I don't buy either argument. While I haven't done full-up XP, I've certainly done test-first development a la XP quite effectively, using AUnit and the capability in Glide for generating its boilerplate code. I also approximate DbC using pragma Assert. It works well, and is within the spirit of XP. GNAT is quite fast enough for test-first flavored development, as you tend not to have a lot of context in unit tests. Admittedly, refactoring would be easier without manifest typing, but that's a tradeoff, and tool support is possible. - Ed disclaimer: ACT employee
