iterator_adaptors Comment

There is a comment in iterator_adaptors:

public: // implementation details (too many compilers have trouble when
these are private).
    Policies& policies() { return m_iter_p.second(); }
    const Policies& policies() const { return m_iter_p.second(); }
    
    Base& iter() { return m_iter_p.first(); }
    const Base& iter() const { return m_iter_p.first(); }

This seems to imply that iter() and policies() ought to be private. I
would like to suggest that having access to the underlying iterator is
valuable. This is especially true of transform and projection iterators
which allow you to locate a record by searching on a field. Access to the
underlying iterator gets access to the rest of the record.

Is there some other way of accomplishing the same thing without using iter()?

Thanks,
