Score one in support for this, from the "peanut gallery" of "experienced
programmers in other languages, but only around 2 years of Go". I thought
at first that if err != nil { ... } seemed clumsy, but I myself don't like
exceptions and implicit flow control constructs much and the more I used
Go, the more natural it felt. If anything, a way to pretty-print stack
traces would be the main thing I'd like to more quickly parse failure
paths, though I have seen at least one project already that does this so it
needn't be a core part of the language.A gofmt one-line with return style as described here seems like a very nice balance to me.
