I did briefly try to fix D support in Meson for a while, but in 
the end, the lack of tracking module dependencies caused too much 
issues during development, so I just gave up and fell back to 
using DUB. Doing full rebuilds also was not an option for me 
because it would take too much time to compile compared to build 
times with DUB.

I might reconsider contributing for better D support once 
Makefile support (https://github.com/dlang/dmd/pull/11357 or 
https://github.com/dlang/dmd/pull/6961) gets accepted.
