This is a truly unreal level of blub paradox and/or brown nosing. It's almost a complete inversion of reality.

Go's maintainers had to be beaten into bolting on a poorly-done implementation of polymorphism over like a decade. I can't imagine anyone who's used any language with polymorphism baked in to the design describing Go's implementation as "exceptionally well designed". If this is a Poe's law thing and you're just joking, then you got me.
