You can do fast incremental builds with D by not putting all the files on the command line. Just put one.

I have an idea or two. I just need time/mental energy to do this.

I don't build the compiler command-line myself, nor do I want to. Even then, recompiling one file isn't useful to me, what is is to recompile what's needed and run the tests. Emacs/flycheck already highlights compilation errors in just one file.

Are you aware of this great work: https://github.com/dlang/dmd/pull/7239?

Isn't that what a build system is for?

I don't understand. C++ compiles files one at a time. You can do the same in D. How can this model be useful in C++ but not with D?

D modules are like C++ headers.  Change one, and you need to recompile everything that imports it.

That's right. That doesn't mean that D should incrementally compile slower than C++.

Yes, and I wrote one. It turns out that I misunderstood what Walter said though.

I wasn't, thanks for pointing it out. Looks interesting, but all the compile times were still over a second, which is my pain threshold.
