Nice summary! (readmore is spoily)

You missed a subtlety about godel, though. What it's actually doing is nesting anonymous calls to the sub returned by escher, which do the extraction from @U. The whole thing returns a sub, which calls more subs nested in the closure, and so on, and so on; that's the part I think is cool.

godel is equivalent to foldr in Language::Functional (or Haskell, for that matter); escher is the combining function, and sub {"\n"} is the start value.
