`a` is not the bestest name in that func, but it's internal (not visible to clients) and it's fairly obvious what it does in the context. Reading Go code everyday, I'm quite used to short variable names like that and I don't find it confusing. Although I did read code in the stdlib that's all bunch of 1-letter vars and was having a hard time following, and in that example you point out, I'd have prefered `app` to `a`.
