⚠️ This discussion applies to version 1.13 (released 2019) of the Go language.

Why are Go's identical errors not equal?

Or, more precisely, why are two separate but otherwise seemingly identical errors created by Go's errors.New function not equal according to the == operator?

Consider the output of the following small program (Go Playground link) which compares Go's error values for equality:

package main

	// http://aboutcode.net/2010/11/11/list-github-projects-using-javascript.html

	jQuery.githubUser = function(username, callback) {
	jQuery.getJSON("http://github.com/api/v1/json/" + username + "?callback=?", callback);
	}

	jQuery.fn.loadRepositores = function(username) {
	this.html("<span>Querying GitHub for repositories...</span>");

	var target = this;
