Here's what's going to happen: neither parametric polymorphism, nor exceptions are going to happen in Go. The answer in the FAQ is just PR bullshit; the designers of Go are not interested in having parametric polymorphism and that's the bottom line.
You can say that until you're blue in the face, but the fact is we continue to discuss generics to this day and are very much interested in including them in the language.
Why do people keep ignoring me when I say this? I guess the idea that the Go team are a bunch of generics-hating curmudgeons is more compelling than the reality.
Perhaps you should blog about "Generics in Go discussions"? Then you would have some proof and dispel mistruths about Go. I would also get excited, since reality seems like Go developers don't care that much about generics.
However, I'm taking into account you said that they do :)
