Summary:
- This article discusses a technical concept called TVAR (Type-Variant-Argument-Return), which is a way of organizing and structuring code in functional programming languages.
- The author explains how TVAR can be a "subtle footgun" or a potential pitfall for developers, as it can lead to complex and hard-to-maintain code if not used carefully.
- The article provides examples and insights on how to effectively use TVAR to create more robust and maintainable software, especially in the context of functional programming.
