interval customization results in compilation errors

[opium]

Changing of interval bounds type in example boost/libs/icl/example/custom_interval_/custom_interval.cpp to static_closed leads to:

boost/icl/concept/interval.hpp: In function 'typename boost::enable_if<boost::icl::has_static_bounds<Type>, bool>::type boost::icl::lower_less(const Type&, const Type&) [with Type = MyInterval]': boost/icl/concept/interval.hpp:877: instantiated from 'typename boost::enable_if<boost::icl::is_interval<Type>, bool>::type boost::icl::lower_less_equal(const Type&, const Type&) [with Type = MyInterval]' boost/icl/concept/interval.hpp:1199: instantiated from 'typename boost::enable_if<boost::icl::is_static_closed<Type>, Type>::type boost::icl::right_subtract(Type, const Type&) [with Type = MyInterval]' boost/icl/concept/interval_set.hpp:249: instantiated from 'typename boost::enable_if<boost::icl::is_interval_set<Type>, Type>::type& boost::icl::flip(Type&, const typename Type::segment_type&) [with Type = boost::icl::interval_set<int, std::less, MyInterval, std::allocator>]' boost/icl/concept/interval_associator.hpp:772: instantiated from 'typename boost::enable_if<boost::icl::is_intra_derivative<Type, AssociateT>, Type>::type& boost::icl::operator^{=(Type&, const OperandT&) [with Type = custom_interval()::MyIntervalSet, OperandT = MyInterval]' custom_interval.cpp:80: instantiated from here boost/icl/concept/interval.hpp:728: error: 'const class MyInterval' has no member named 'lower' boost/icl/concept/interval.hpp:728: error: 'const class MyInterval' has no member named 'lower'}

Using of insert method with iterator arguments also results in compilation error.

New version of void custom_interval () from the same source file boost/libs/icl/example/custom_interval_/custom_interval.cpp (with interval_bound_type <MyInterval>::value = interval_bounds::static_right_open):

void custom_interval()
{
    // Now we can use class MyInterval with interval containers:
    typedef interval_set<int, std::less, MyInterval> MyIntervalSet;
    MyIntervalSet mySet;
    mySet += MyInterval(1,9);
    cout << mySet << endl;
    mySet.subtract(3) -= 6;
    cout << mySet << "            subtracted 3 and 6\n";
    mySet ^= MyInterval(2,8);
    cout << mySet <<      "  flipped between 2 and 7\n";

    MyIntervalSet::iterator it = mySet.insert (mySet.end (), MyInterval (6, 8));
}
