   * olsner: I think doing eta something means to make it more or less
     pointless. But I don't recall which eta does what

   * mm_freak: Oleg knows what's at the end of foldr f z [1..].

   * copumpkin: it's like grasping desperately for the rope of induction
     as you fall down the bottomless pit of coinduction
