Is worse in the sense that you have the feeling that is free in D, but it's not. In C++ you *have* to be careful, otherwise the compiler eats you. In D, when this starts to be significant, you already have a huge project. And again, I agree that it might be a very reasonable trade-off, but that doesn't mean the problem doesn't exist. That's all. I'm not trying to convince anyone that C++ is better, I'm just saying in C++ the problem is obvious while in D is much less visible, and you note it *only* when your project is big enough and you *need* incremental compilation. And I know also that DMD (and every DMD-based D compiler) can generate .di files. It would be really nice to have a -M option like GCC that automatically writes Makefile dependencies. But that's another topic. -- Leandro Lucarella (AKA luca) http://llucax.com.ar/ ---------------------------------------------------------------------- GPG Key: 5F5A8D05 (F8CD F9A7 BF00 5431 4145 104C 949E BFB6 5F5A 8D05) ---------------------------------------------------------------------- A veces quisiera ser un barco, para flotar como floto siendo humano, y no hundirme como me hundo
