Yeah, I noticed that `ed` invocation in the rc manual. I'm tempted to find use-cases for it. That way I can lay claim to having used the one true editor :)

In general, I like making programs out of declarative constructs and/or literal data, because it's so much easier to do "local reasoning" with those things, as compared to imperative procedures, or heaven forefend, live objects.
