An issue with recursive functions is that they may raise a stack-overflow error if the number of recursive calls is too high. To avoid these errors, many functions in Tezos are written in tail-recursive style. This style is usually harder to read and this could lead to mistakes in the code. We show in this post how we verify a tail-recursive function by comparing it to its naive non tail-recursive version.
