My least favorite part of Go, by far, is the capitalization as struct member visibility thing. That and the not super great json encoding annotations.

Here's a sample:

type Change struct {
	Path             string `json:"path"`
	Category         string `json:"category"` // change, append, create, delete
	Position         int64  `json:"position"`
	Size             int64  `json:"size"`
	OriginalChecksum string `json:"original_checksum"`
	UpdatedChecksum  string `json:"updated_checksum"`
	UnixTimestamp    int64  `json:"unix_timestamp"`
	Data             []byte `json:"data"`
	MatchedRules     []Rule `json:"matched_rules"`
}

I would take explicit public declarators any day
