In C++ incremental rebuilds are simple as you compile each file individually anyhow, but that's the crux for why C++ compilations are so slow in the first place. Compiling multiple modules at once provides lots of speedups as you do not have to reparse and analyze common/mutual imports, but on the downside it cannot be parallelized that well.
dub supports --buildMode=singleFile --parallel to mimic that, but it's very wasteful.
For example gtk-d took way over a minute with single file compilation, but only a few seconds when being compiled at once
