AIUI, Go intentionally avoids programming language features considered too advanced by its authors in order to lower the bar (to make it easier for most programmers to pick up, that is) and to keep the code uniform, supposedly to the advantage of companies using it. While hammering unidiomatic approaches into a language virtually always is awkward: there are other libraries and programmers, even if you are fine with the rules you have to follow in order to emulate the desirable features using a library. The combination of those things looks even stranger than they do separately.
