I Love Go; I Hate Go
The most frustrating thing for me, by far, is that Go won't let you import unused packages. When you are commenting stuff out to debug a program, or adding debug statements and removing them later, it constantly requires you to go back to the top of the file and comment out the unused libraries, only to uncomment them later when you've solved your problem.The fact that there is not a compiler flag to disable this behavior, and that the core team is opposed to adding such a flag (https://golang.org/doc/faq#unused_variables_and_imports), is simply ridiculous and makes programming in Go a real pain in the ass.I can't think of any other language that does this.
