Notes from the February, 2014 meeting:

CWG agreed that the example should be ill-formed.

[Adopted at the November, 2014 meeting as part of paper N4268.]

It is not clear whether naming a member of a global anonymous union should be considered an id-expression or implicitly a member access expression. For example, given

  static union {
    int i;
  };

  template <int &> struct S {};
  S<i> V;

is the last line well-formed? There is implementation variance on this question.
