Just pointing out that it was not really as novel as you seem to believe it was at the time it came out.

Ok, sure. There were no other native garbage collected languages. Ignoring history, this is true.

If we ignore history again, also new with Go.

I can't think of an equivalent in the form of syntax, so sure. This is a point to Go. It's a small change, but useful for flattening code.

> No while loop?!?

I don't know why the exclamation mark. They have one named type of loop with `for`, but they definitely have a while loop:

  for x <= 10 {
    ...
  }

That's a while loop, it's not an infinite loop, it's not a do-while loop. That they reduced their looping constructs to one name (and then determine which actual loop kind by what's between `for` and `{`) does not mean they actually removed while loops. This does simplify the syntax, maybe.

[edit: missed this one]

  if (some_c_lib_fun(...) == -1) {
    // check the errno
  }

I didn't. Why are you putting this here?
