I think by the time I have a massive project where compile times could actually hurt the newest endeavor with compiling to an intermediate form, etc., will already be released so it's likely that I'll dodge that entirely. For what it's worth I haven't found any language constructs that seem to make the compile time grow considerably, so I think the risk of adding a library and suddenly being faced with massive compile times is fairly low in comparison to some languages. With that said, I'm only using the core lib and vendor libraries. JangaFX by way of GingerBill reports that their 200kloc EmberGen[0] project takes 5 seconds to compile: > On my old machine, it took 5 seconds, and now it takes 2.2 seconds on my new machine. Before some paths in the compiler had multithreading added to them that number was 15 seconds for the same project. As far as I know both of these numbers are for unoptimized builds, i.e. development builds.
