hello

unordered_map provides
iterator insert(iterator hint, const value_type& obj)
     AND
const_iterator insert(const_iterator hint, const value_type& obj)
which is reasonable. Changing a container is not the same as changing
an element.

However,  map provides only
iterator insert(iterator hint, const value_type& obj), i.e.
it does NOT provide the const_iterator variant.
(The same problem ist with erase(...)).

Is there a reason, why std::map does not provide the const_iterator
variants?

Uli
