Things I dislike:
- if err != nil. Just give me some syntactic sugar instead of letting me write the same thing a bajillion time.
- no way to bind a struct to an interface. I'd like my IDE to tell me when I accidentally stopped implementing an interface
- some stdlib parts are too bare bones. Unpacking an archive requires me to handle all files, directories, links, etc. myself. There is no move command that can move a file or directory across fs boundaries. The little things.
