Author here. The fact that `strings.ReplaceAll` exists I think is a good argument for having default arguments, because I can't think of a good reason why we need a separate function for this case. But maybe it was a bad example. I remember that there is one function in `strings` that I almost always use the same value in every call I do because it is the correct value in 80% of the cases. I thought it was `strings.Replace`, but probably it is something else. If I ever remember which function it is, I will update the post.
