Comment (by Laurent Rineau <Laurent.Rineau__boost_at_[hidden]>):

 As far as I have understood, when
 `iterator_facade<Derived,Value,Category,...>` is instanciated, the type
 `Value` is required to be complete because of the following member
 function prototype:
 {{{
 typename detail::operator_brackets_result<Derived,Value,reference>::type
 operator[](difference_type n) const
 }}}
 which triggers the instanciation of
 `use_operator_brackets_proxy<Value,Reference>` (in the same file), which
 triggers the instanciation of `is_POD<Value>`, which requires a complete
 type.
