Exactly. All you really need to know is how to accomplish things in functional, OO and procedural languages. The advice given in the article is very nearly syntax based, not conceptual. Which is nearly useless if you're going very far from C/++.

If you're in a procedural language the questions is: what's the for-loop?

If you're in an OO language: are there iterators, how do I use them?

If you're in a functional language: what the syntax for mapping, etc.
