There's a lot of tricks you can do to optimize build times, and I've tried most of them in my previous game engine. Got ~90kloc recompilation time from 15min to something like a few minutes, although that required rewriting a bunch of code to not use templates. And removing boost. Multiple days' work. But the point is, that I'd like a language that is fast to compile by default. C seems pretty promising, as doing a full unity build of my 25kloc codebase takes something like 3 seconds. Not sure how much of that is actually compilation, and how much IO. I'm expecting the project to grow to something like 100-200kloc, and hopefully never have to spend time figuring out why the compilation takes too long, and instead use that time to do something productive.
