Section: 11.4  [class.mem]     Status: TC1     Submitter: Jason Merrill     Date: 5 Dec 1998

Between the May '96 and September '96 working papers, the text in 11.4 [class.mem] paragraph 13:

If T is the name of a class, then each of the following shall have a name different from T:

    In addition, if class T has a user-declared constructor (11.4.5 [class.ctor] ), every nonstatic data member of class T shall have a name different from T.
