The literal 0xffu8 in Rust is pretty tricky to read without syntax highlighting. It looks like a plain hexadecimal value at first. (Why not have syntax highlighting? Ironically I was debugging and improving VS Code's Rust highlighting.)

I bring you a message about a language that has been at the birth of many others, but almost no one knows it. A rumor of a graphical environment offering options like no other, but almost no one using it. I also bring information about a virtual machine supporting reflection almost to infinity, reaching almost half of the operating power of C in numerical calculations in its time, yet today forgotten.
