/*
Use operator `const_iterator` instead of `const_iterator(const iterator&
other) noexcept` to avoid two class definitions for @ref iterator and
@ref const_iterator.
This function is only called if this class is an @ref iterator. If this
class is a @ref const_iterator this function is not called.
/*!
@note The conventional copy constructor and copy assignment are
implicitly defined.
Combined with the following converting constructor and assigment,
they support: copy from iterator to iterator,
copy from const iterator to const iterator,
and conversion from iterator to const iterator.
However conversion from const iterator to iterator is not defined.
