That and other things too. It's definitely the new C IMO. I like how the author contrasts it with Java, "There were many things that did not copy across due to the comparative richness of the Java libraries...". Of course, I like Java about the same as I like Go (both great languages). But if you are used to the wealth of pre-made data structures in Java you'll find arrays, slices and maps in Go to be somewhat limiting at first. You'll soon get it though and start doing really cool things with Go.
