Yes, you do recall correctly. From section 1.8 of HOP (page 33 in my version):

Sometimes a problem appears to be naturally recursive, and then the recursive solution is grossly inefficient. A very simple example arises when you want to compute Fibonacci numbers. This is a rather unrealistic example, but it has the benefit of being very simple.
