Boost C++ Libraries: Ticket #682: Constness in iterator_facade::operator-> https://svn.boost.org/trac10/ticket/682 <pre class="wiki">The C++ standard states (table 72) that for an input iterator, a->m is equivalent to (*a).m. If operator* returns a value_type by non-const value, it is possible to call a non-const member function on the temporary returned from the function. However, the operator_arrow_proxy class acts as a proxy to T const* rather than T*, this that you can do (*i).non_const_method(); but not i->non_const_method(); for certain input iterators.
