Is f'(f'(A,B),C)) the same as F(A,B,C)? If so, then just run a loop on your array of strings, replacing the first two with the results if f'(A,B). By the time you are down to a single string left, you will have the same results as F(A,B,C,....).

List::Util's reduce function can be helpful in implementing this.
