I just don't agree with adding more syntax to the language for what basically amounts to an if statement. If it's a conditional, which it is, just use an if statement.

Look at all the monad tutorials for Haskell. Nobody knows how to use the special syntax for Maybe and Either. They read hundreds of articles and still don't get it. Meanwhile, everyone understands how "if err != nil" works, perhaps too well, which is why they complain about it.
