So sidju says to themselves, hey, let's add syntax highlighting to ed. Kids, this is how you break the eternal seals on the hellmouth, and is also why we can't have nice things.

It is just so easy to run, easy to use, can open multiple files and is so readable. Why would I open an editor when I'm already in a terminal and it's right there?
So the feature makes perfect pragmatic sense.
