Maybe this is just my experience, but it took me far longer to understand the subtleties of move semantics, rvalues, and RVO than to understand pointers and references in C++. And this is not even getting into “universal references” (which I don’t have a comfortable understanding of either)

There's a YouTube video [1] of a great talk by Scott Meyers: Effective Modern C++ (part 1). He covers universal references and how they relate to other kinds of references in either that one or Part 2 [2]. I found the videos very helpful.

Edit - I may have the wrong videos linked. It could be his talk on Universal References [3] that I'm thinking of. It's been a while.
