Ada, Its Design, and the Language That Built the Languages
Summary
The article argues Ada's design introduced enduring concepts that influenced modern languages, including a strong module system with a clear interface/implementation separation and representational hiding. It also covers Ada's concurrency model, rich type system, and generics, along with SPARK formal verification, contracts, and the annexes that enable certifiable systems. The piece suggests that contemporary languages converge toward Ada's solutions, underscoring reliability and formal methods in safety-critical contexts.
