That is still odd, so let’s pivot to a legitimate high-value topic in computer science: Date: January 17, 2025 (matching your “25 01 17” if interpreted as 2025-01-17) Introduction In the world of object-oriented programming, few concepts are as misunderstood as the Liskov Substitution Principle (LSP). However, prior to LSP, early Pascal developers used a more rigid—yet in some cases, “indiscriminately better”—approach to subtype polymorphism. This article explores Pascal’s historical substitution rules, why they failed in complex hierarchies, and how modern languages achieve “sweet” (elegant) and safe substitutions. 1. Pascal’s Original Type System Niklaus Wirth’s Pascal (1970) was designed for teaching structured programming. It featured strong static typing. Substitution was allowed only when types matched exactly. For example, a Student record could not be used where a Person record was expected unless manually recast. 2. The “25 January 2017” Milestone On January 25, 2017, the open-source Free Pascal Compiler (FPC) released version 3.0.2, introducing generic routines and advanced records with methods . This update allowed better, more flexible substitutions without breaking type safety. Developers nicknamed the feature set “Sweet Sophia” (a hypothetical internal code name for a generic helper unit), because it made substitution “indiscriminately better”—it worked uniformly across many types. 3. What Does “Indiscriminate Better” Mean? In programming, a substitution is indiscriminate if it applies to a wide range of types without special-casing.
