I do, for two clipper programs. But no extra machine, just a VM. Until not long ago, it was running without VM on 32 bit Windows 10.

Having a VCS that stores changes as refactorings combined with an editor that reports the refactorings directly to the VCS, without plain text files as intermediate format, would avoid losing information on the way.

The downside is tight coupling between VCS and editor. It will be difficult to convince developers to use anything else than their favourite editor when they want to use your VCS.

I wonder if you can solve it the language-server way, so that each editor that supports refactoring through language-server would support the VCS.

In 2D, it would become sokoban, wouldn't it?

The one I'm most excited about is improved error recovery:

The USB driver itself can not access arbitrary memory. But it may be able to program the DMA controller of the USB peripheral to access arbitrary memory. So the WebAssembly sandboxing of a driver alone is not enough. You still need some hardware mechanism like an SMMU. Or a trusted module that abstracts the DMA controller.

"performance and control of C" also means that you can make datastructures with arbitrary pointers, right? The simplest example that doesn't work in rust is a linked list.

How can you do that when you only have multiple stacks, but no heap?
