@@ -802,12 +802,14 @@ object. Is all this mechanism really necessary?
c++std-lib-12333:
N1550 requires that for a Readable Iterator a of type X, ``*a`` returns an object of type
iterator_traits<X>::reference. ``istreambuf_iterator::operator*`` returns charT, but
istreambuf_iterator::reference is charT&. So am I overlooking something, or is
istreambuf_iterator not Readable
``iterator_traits<X>::reference``. ``istreambuf_iterator::operator*`` returns ``charT``, but
``istreambuf_iterator::reference`` is ``charT&``. So am I overlooking something, or is
``istreambuf_iterator`` not Readable.
:Proposed resolution: **Needs language** (Jeremy)
Remove requirements on the reference type from Readable Iterator.
:Proposed resolution:
Remove all constraints on ``iterator_traits<X>::reference`` in Readable Iterator
and Lvalue Iterator. Change Lvalue Iterator to refer to ``T&`` instead of
``iterator_traits<X>::reference``.
