Someone is rediscovering literate programming where the code is so meaningful it serves as documentation of itself.

I vote for a troll disguising a boring scheme tutorial in a satire.

But it is very metaphysical à la Artistote or Giodarno Bruno ... I would say like almost any stuff written by the functional programming adepts. I am not sure if FP is mathematics or philosophy sometimes. I like them like some weird religious monks producing free beers. I drink the beer, I avoid the church.

But I would say that even if I do not like scheme, I value meaningful code too.
