Handling so-called edge cases in data structure design - an example of a cookbook

In Hillel Wayne's article titled "Edge Case Poisoning", the author examines the issue of avoiding dependency on edge cases in programming. He defines "edge case poisoning" as a situation where developers start to shun solutions that might be useful in unexpected scenarios, leading to significant problems down the line. Hillel provides several examples to illustrate how excessive caution in code development can result in applications that are inflexible and difficult to maintain. The author suggests that instead of entirely avoiding tough cases, programmers should strive for a balance, accepting some risks in the name of long-term usefulness. Many of the issues raised revolve around the lack of flexibility in software design and the necessity for clear communication within development teams, ensuring all members share a consistent vision of problems to avoid.
