However per the suggestion at the top of the present thread the compiler already knows where [ and ] signify a generic. So if the user wants to use an identifier that begins or ends with a _ then in those spots the user must include the _ rather than have gofmt add it. (Since gofmt would add a _ if there is no leading or trailing _ at those spots but wouldn't add one if there is one.) In other words if you want to use the identifier _x then you would end up with [__x_], if you want to use the identifier x_ then you would end up with [_x__] and if you want to use the identifier _x_ (which is allowed in Go) you would write [__x__]. I think this is rare. Keep them coming! More corner cases? -- You received this message because you are subscribed to the Google Groups "golang-nuts" group.
