I see a lot of posts about the speed of dmd. I've been basically 
using ldc exclusively when I switched to mac M1, and, I haven't 
been very disappointed.

I'll say this, compiling my work project with dmd is 100x slower 
than compiling my personal projects with ldc.

I don't know if it's LLVM, is all I'm saying.
