Most of my complaints, I feel like are pretty well documented: No ability to do Generics, no ability to do operator overloading, no ability to make your own for each style loop objects, very manual and repetitive error handling. These are all simplifications to the language spec at the expense of more complicated usage. For the most part, I've been trying to understand myself how to express why I get a pretty bad taste in my mouth when using or looking at Go code, why it feels so much less productive to me than the higher-level languages. Which is what it has been making dents in more than anything else. I especially wanted to understand this since I do see myself as someone who values simplicity. In the end, it's because I value simplicity in usage, rather than the simplicity be in the language constructs. I'd instead rather learn a slightly more complicated language, and be more productive with every task I write using it. I don't see Go users as cavemen. That was admittedly an exaggeration to express my point clearly.
