Two serious problems:

  1.  "branches" expects a method name not an expression.
      Use "branches_expr" when you want an expression

  2.  It is not very wise to generate a tree with a branches
      expression that is independent of its context.
      You will get an infinite (lazy) tree where each node has
      the same children.
