I expect that once we get generics we are going to get a host of differently implemented variations of the error monad none of which is used by the standard library. Which I think is worse then try. In a broader sense I am deeply irritated by the part of the go community's culture that seemingly sees any effort to make go more "don't repeat yourself" to be making it more complex. With no acknowledgment that avoiding complexity in the language isn't a free lunch, it comes at the cost of complexity in the code written, the ecosystem and libraries.
