"Move" in the sense of https://stackoverflow.com/questions/3106110/what-is-move-semantics https://stackoverflow.com/questions/3106110/what-is-move-sem... Now, if you don't know what "move semantics" is, then "lvalues can't be moved from" isn't terribly helpful, and if you do then it's tautological, so I'm not saying you're wrong to criticize. :) But in a C++ context, "move" does have a single specific meaning — the one he's using properly if opaquely-to-non-C++ers.
