410. Missing semantics for stack and queue comparison operatorsSection: 23.3.11.2 [list.cons], 23.3.11.4 [list.modifiers] Status: CD1 Submitter: Hans Bos Opened: 2003-06-07 Last modified: 2016-01-28

Discussion:
Sections 23.3.11.2 [list.cons] and 23.3.11.4 [list.modifiers] list comparison operators (==, !=, <, <=, >, =>) for queue and stack. Only the semantics for queue::operator== (23.3.11.2 [list.cons] par2) and queue::operator< (23.3.11.2 [list.cons] par3) are defined.
Proposed resolution:
Add the following new paragraphs after 23.3.11.2 [list.cons] paragraph 3:
operator!=Returns:
x.c != y.coperator>Returns:
x.c > y.coperator<=Returns:
x.c <= y.coperator>=Returns:
x.c >= y.c
Add the following paragraphs at the end of 23.3.11.4 [list.modifiers]:
operator==Returns:
x.c == y.coperator<Returns:
x.c < y.coperator!=Returns:
x.c != y.coperator>Returns:
x.c > y.coperator<=Returns:
x.c <= y.coperator>=Returns:
x.c >= y.c
[Kona: Matt provided wording.]
Rationale:
There isn't any real doubt about what these operators are supposed to do, but we ought to spell it out.
