Software engineer Hillel Wayne shares persistent gripes with Prolog, the logic programming language. Writing for his 'Logic for Programmers' guide, Wayne highlights fundamental usability issues that complicate real-world development.

Key complaints include non-standardized strings, lack of proper functions, and missing boolean values. The language's cut operators create unpredictable behavior, while collection types remain limited to lists and compound terms. These limitations hinder expressiveness.

Wayne contrasts Prolog with Picat, a newer language addressing many of these flaws while preserving bidirectionality. Though Prolog retains academic interest, these persistent design choices limit its adoption among working programmers seeking reliable, cross-compatible tools.
