title: Name used in the static data member definition after unqualified id
body: <p>From the sec. 3.4.1/13 of N3797:</p>
  
  <blockquote>
    <p>A name used in the definition of a static data member of class X
    (9.4.2) (after the qualified-id of the static member) is looked up as
    if the name was used in a member function of X.</p>
  </blockquote>
  
  <p>it is unclear how is looked up a name used in the definition of a static data member of class X after the <strong>unqualified-id</strong> of the data member. I need a quote from the standard.</p>
