This article explores the concept of "guarded methods" in object-oriented programming, a feature that allows constraints to be applied to the receiver (self) for specific methods. While languages like OCaml, Java, and Kotlin do not directly support this syntax, the author demonstrates how to implement guarded methods in OCaml using type equality witnesses. The discussion covers alternative approaches such as moving methods outside the class or using extension methods, ultimately advocating for the guarded method approach for its ideological purity and precise receiver characterization.
