On a different topic. I’d like to develop similar things for 
AAarch64, but that’s an instruction set that’s new to me, so a 
new learning curve. Do any of our members have ARM64 asm 
experience and if so would they recommend tutorials for 
experienced asm programmers, beyond what I can google for myself, 
obviously, and the ARM official docs of course. And any tips on 
starting out as some stuff looks weird, such as the usage of the 
carry flag, and the bizarre x / w register width conventions.
