Lack of Default Interface Implementations and Reflection Dependency

6/10 Medium

Go lacks default implementations for common interfaces and relies on runtime reflection to handle operations like printing structs or maps, which sidesteps the type system entirely. This creates ad hoc, edge-case-laden behavior.

Query: “What are the most common pain points with Go for developers in 2025?”3/29/2026

Default implementations for certain interfaces should be provided. How can Go print out our structs or maps correctly? We don't know. It is done with reflection, which is runtime concept and sidesteps the type system entirely.
