It is. Although, as far as I'm informed (having last used it in 2013 or so), even with that approach, you'll likely have problems linking all the output in the end if your project is large enough.

Of course, thats another separate problem to begin with. I still remember dabbling with D and vibe.d and replacing the default GNU linker with ld.gold because over 90% of the build time was due to the linker...
