 The problem, recall, is to take two trees and decide whether they have

 So `ta` and `tb` are different trees that have the same fringe, but

+We've seen two solutions to the same fringe problem so far.  
 The simplest solution is to map each tree to a list of its leaves,
 then compare the lists.  But because we will have computed the entire
 fringe before starting the comparison, if the fringes differ in an
