Hello Gophers, There's two tiny pieces of syntactic sugar I really miss from a few other languages that I think would add a nice bit of ergonomics and convenience to Go (which I now play as my main) without increasing any magic or spooky action at a distance.
They are: - postfix conditionals and - until (while!) and unless (if!) (which probably also means adding `while`) This allows for lovely expressions such as the following examples: i.NotifySomeone() if j.HasExpiredItems() time.Sleep(1 * time.Second) until thing.IsReady() b.ReportActivity(e) unless u.HasOptedOut() q.ProcessItem() while server.Active() until(time.Now().After(notAfter)) { // do something while we still can } p.processEvents() until p.shutdownRequested and, my favorite: panic("can't even") if err != nil There are, of course, various ways of doing some of this sort of synchronization stuff in these contrived examples using channels/goroutines/timers, but this sort of syntax is quite useful for simple straight-line synchronous code, and, in my view, increases readability without sacrificing anything. I know that `while` isn't a distinct thing in Go, and for consistency's sake, this might necessitate adding such a construct as well (if you can use it as a postfix conditional, you should probably be able to use it as `while(cond) {}` too). What do you think? I really miss this syntax from other languages. It's been in Perl and Ruby for ages, and, more recently, CoffeeScript had it for a moment, but it didn't make it over into ES with the other notable features from it. I think it's a lovely convenience without changing the operation of the language itself.
