Go subtleties

I balked a little when the article refers to format strings as "string interpolation" but there's multiple comments here running with it. Am I out of date and we just call that string interpolation these days?

I also found this very confusing:

> When updating a map inside of a loop there’s no guarantee that the update will be made during that iteration. The only guarantee is that by the time the loop finishes, the map contains your updates.

That's totally wrong, right? It makes it sound magical. There's a light explainer but I think it would be a lot more clear to say that of course the update is made immediately, but the "range" iterator may not see it.

"Am I out of date and we just call that string interpolation these days?"

It's all just spelling. Your compiler just turns

    x = "I want ${number/12|round} dozen eggs, ${name|namecase}"

into

    x = StrCon("I want ", round(number/12), " dozen eggs, ", namecase(name))

anyhow. It's not a huge transform.

I think people get bizarrely hung up on the tiny details of this between languages... but then, I think that extensive use of string interpolation is generally a code smell at best anyhow, so I'm probably off the beaten path in more than one way here.
