Which people like to bring up, and does make it "possible" to do this style, but takes a style I think is already crazily and uselessly verbose and makes it even more verbose, especially once you take that "strconv.Atoi" and try to inline a function there, at which points the types from the earlier generic instantiation get to appear again. Hope you didn't give your types good, descriptive names! As a potentially useful technique in the general sense it makes good sense to know. As a solution to making map & reduce practical functions to use in Go, it makes me wonder just how much crap it takes for people to notice that just because a pattern is fun to use in one language, it isn't appropriate for another. I mean, how painful does it have to be, exactly? Also, some people just insist on chaining, which this won't enable. (At least not without even more gymnastics.)
