Matthew Wilcox recently realized there might be a value in depending on C extensions provided by the Plan 9 variant of the C programming language. All it would require is using the -fplan9-extensions command-line argument when compiling the kernel. As Matthew pointed out, Plan 9 extensions have been supported in GCC as of version 4.6, which is the minimum version supported by the kernel. So theoretically, there would be no conflict.

I recently created a video demonstration of how to do some work at the command line, but as I tried to record my video, I kept running into problems. I'm just not the kind of person who can type commands at a keyboard and talk about it at the same time. I quickly realized I needed a way to simulate typing, so I could create a "canned" demonstration that I could narrate in my video.
