@cstross Wow! This is a great example of the power of virtual platforms, #emulators, and also disciplined state control in a programming language. The fact that you can run this inside a #pdf is also instructive — yet another attack vector.
Also, I’ll bet there are many packages out there to do cross-compilation from #RISC-V to other machines. Remind me never to use Adobe Acrobat.
