It is very easy for programmer to write statements that cause infinite loops resulting in total program failures. [39] Indexing only affects program performance, it does not affect semantics. It has clarified aspects of the language that were previously ambiguous and leads to portable programs. Therefore, deterministic tail-recursive predicates are executed with constant stack space, like loops in other languages.
