Commands like go run, go build and go test amoung others should have coloured output when an error occurs. it would make reading stack traces a lot easier. I personally use the go run tool a lot during development because I have no reason to keep a binary in the $GOPATH/bin directory when it's

Re: [go-nuts] Plurality of package naming

That's advice for a very different style of language than Go. Go does not have "objects" in the sense of that post. A Go interface, for example, does not "have lots of instance variables, lots of arguments, and pass lots of data around probably." A class is not a struct is not a Go interface.

You need compare the result with one summand to detect overflow. See here: https://play.golang.org/p/3Uh0eFSbQW Programming languages usually don't provide access to machine level flags, because they support combining multiple operations in one expression. For example what should the carry
