If I understand Iain’s reply correctly, the showstopper was lack 
of support for AArch64 / MacOS in GCC at the time. Has that 
situation improved by now ?

If the situation now makes either downloading or building GDC / 
AArch64 / MacOS from sources possible, would someone be kind 
enough to knock up a shell script for me ?

NB I do have a working GDC/Linux on an x86/64 box now, so I can 
compile D programs on that machine, with GDC, and also to AArch64 
using LDC on my Mac M2 machine.
