I like Go. I really want it to succeed as a language. However, it does have some unfortunate warts. To me, one of the biggest issues is the lack of true exceptions. Exceptions that show the call stack (as in Java and .NET) take a lot of the mystery out of real-world troubleshooting an issue with a third-party library (for example). Panic or returning an error doesn't provide the same utility.
