Discussion:

[back.insert.iter.cons]/1, [front.insert.iter.cons]/1, and [insert.iter.cons]/1say "Initializes container with&x", which doesn't defend against containers overloadingoperator&().Containers are now required to have such defenses for their elements, so we may as well be consistent here.

[Issaquah 2014-02-11: Move to Immediate]

Proposed resolution:

This wording is relative to N3691.

1. Edit [back.insert.iter.cons]/1 as indicated:

   explicit back_insert_iterator(Container& x);

   -1-Effects: Initializescontainer with&xstd::addressof(x).

2. Edit [front.insert.iter.cons]/1 as indicated:

   explicit front_insert_iterator(Container& x);

   -1-Effects: Initializescontainer with&xstd::addressof(x).

3. Edit [insert.iter.cons]/1 as indicated:

   insert_iterator(Container& x, typename Container::iterator i);

   -1-Effects: Initializescontainer with&xstd::addressof(x) anditer withi.
