But a lot of things that I'm clicking through spend a lot of time describing the architectural-astronaut underpinnings in uselessly vague terms without showing any concrete examples at all or linking to anything at all. What they're saying could apply to any of dozens of programming languages that I've run across, and lots of it applies to literally all of them.

What does this actually do and how do you use it? And how, as a visitor to the WikiLambda project page¹, would I even find that information? Because I am a visitor and I just failed to do so. I can't even tell if this would be interesting to me or not because it said so little in so many words.
