My CS degree (2002-2006) did not explicitly cover "for x in y" iterators. But it did cover an understanding of algorithms and data structures well enough that I could implement one.
That was probably before they were really in style e.g. C# didn't add foreach / iterators until ~2005 with v2.0 and your curriculum probably lags a bit behind the industry state-of-the-art unless it was Ivy league
Which is better? YMMV.
