Use struct{} as keys for context.Value() in Go

In the other file of this gist I detail why we should use struct{} as context.Value() keys and not int or string. Open gist to see main.go but the TLDR is:

	type key struct{}
	ctx = context.WithValue(ctx, key{}, "my value") // Set value
	myValue, ok := ctx.Value(key{}).(string) // Get value
