I'm having trouble using iterators implemented in terms of
boost::iterator_facade with the range-v3 library.

The problem is decltype(it++) which in my case
is postfix_increment_proxy<>, desn't model the Readable concept, because it
isn't DefaultConstructible and doesn't have a ppublic value_type nested
typedef.

To me it seems reasonable to require decltype(it++) to model Readable, so I
created a ticket (a test case and a patch with the proposed solution
included) please see:
https://svn.boost.org/trac/boost/ticket/12071
