One of the most common issues novice Go programmers run into is the inability to pass a slice of a concrete type (e.g. 


[]int64


) into a function that expects a slice of interfaces (e.g. 


[]interface{}


 or something like 


[]fmt.Stringer


). Why is that?

In this post, I'm going to list several answers to this question, diving into some interesting implementation details of how Go works under the hood.
