static variables, methods, functions, and linkage IIRC. But the fifth, and most important of all, is race conditions...

  I think you're double-counting something: 1) static variables outlive function scope 2) static methods don't get a 'this'. 3&4) static functions have no linkage?? I like your fifth though :)

    D'oh! I was thinking that it was a trick question and there was a corollary to <code>extern "C" { ... }</code>. I out thunk myself on that one. Which leaves translation unit variables, class variables (which I had erroneously included in translation unit variables initially), class methods, and translation unit functions.

      If I remember rightly (many many years ago) that's what he was looking for, and to me I struggled because I thought of the two orthogonal effects it conflates: that of lifetime and visibility. From that I had to re-engineer his four, but put (iirc) translation unit variables and functions together. Anyway, the question was 'tell me what I'm thinking', not 'do you understand C++'. But I think between the two of you you might pass :) I remember he was insufferably smug about how good a question it was for sorting out real C++ programmers from wannabes like me :D I knew then I couldn't work with him.
