Consider a function transforming a particular kind of leaf node. With a typical tree data type, we must add recursive calls for every recursive data constructor.

A deductive system is used to demonstrate, on a purely syntactic basis, that one formula is a logical consequence of another formula. There are many such systems for first-order logic, including Hilbert-style deductive systems, natural deduction, the sequent calculus, the tableaux method, and resolution. These share the common property that a deduction is a finite syntactic object; the for…
