Recursion introduction

When an operation needs the method in one class to communicate with a method in another class, then the interface of these two class (the method) should be named the same. If it happens to be the case where such two methods in the same class, then a logical recursive method is formed, this is defined as recursion introduction by Johnson and Foote.

Johnson and Foote call this practice recursion introduction despite the fact that it may not introduce "real" recursion because the method appears to be recursive.

According to Johnson and Foote, the benefit of recursion introduction is to help programmers decide what operations should be methods.
