I see no place in the linked article where this is passed off as an innovation. I see no claim that it is impossible in any other language or that Go is uniquely good at table based testing. All there is is a claim that in the Go community specifically this practice has been getting more popular, and this is a relatively old article now, dating back to the community being pretty young, so it's a sensible claim at the time. I am also not aware of anywhere where the Go designers try to pass anything off as an "innovation". To my eyes they've always been very up front that they're not looking to innovate and that Go was always about recombining established ideas. There is only one thing I am aware of that I have seen from the Go designers where they claimed actual innovation, and it was down in some grotty details about how garbage collection works in Go, and even that was more from the perspective of answering the FAQ "Why don't you just do exactly what Java does?" and giving a detailed answer about relevant differences in the runtime than any sort of "look what we've discovered". If you are reading claims of "innovation" where none exist, I guess this makes sense of your hostility, but are you sure people are actually claiming what you think they're claiming?
