Somehow I don't buy it. If you don't want rich standard for error handling, nothing prevents you from returning just a string as an error. It's just a value, isn't it?

Error handling is generic by itself. This is at the heart of any existing application. It is fundamental part of the design process and later on contributes greatly to troubleshooting. Making this solid should be, IMHO, one of the most important and thought through part of any language. In Go it seems to be left at the developer's convenience. And even though you may say there is a huge debate on the subject, it always leads to nothing. Or almost nothing, like in this case. It's just disappointing.
