What is a `unit`?
A backpack thing. You can save this source as a single file `U.bkp` and build it with `ghc --backpack U.bkp`. In this case it's equivalent to just writing six `.hs` files. (I just learned about this from this ticket.)
How can `N` be bundled with anything (it isn't a pattern synonym)?
It should read "When we look at the interface for D, we see that X is bundled with G", I assume. -- Ticket URL: http://ghc.haskell.org/trac/ghc/ticket/13321#comment:2 GHC http://www.haskell.org/ghc/ The Glasgow Haskell Compiler
