Map[string]interface{} in Go: a user's manual

I don't think "empty" is quite the right mental model. It's an object that has at least 0 methods, which is a characteristic of every data type. An actually empty type in Go is struct{} (good for map values when the map represents a set).

To be clear, "empty interface" is the official term: ctrl+f "empty interface" on https://golang.org/ref/spec

Well the interface's method set is empty, not the underlying type.
