Conflict between boost: type_erasure and boost :: iterator_facade

Consider this very simple program:

#include <boost/type_erasure/is_placeholder.hpp>
#include <boost/iterator/iterator_adaptor.hpp>

int main()
{
    return 0;
}

It won't compile with:

  include/boost/type_erasure/is_placeholder.hpp:31:33: error: reference to 'use_default' is ambiguous
    struct is_placeholder< ::boost::use_default> : ::boost::mpl::false_ {};
                                    ^
    include/boost/iterator/iterator_adaptor.hpp:44:18: note: candidate found by name lookup is 'boost::use_default'
    using iterators::use_default;
                     ^
    include/boost/type_erasure/is_placeholder.hpp:21:8: note: candidate found by name lookup is 'boost::use_default'
    struct use_default;
           ^
    1 error generated.

I don't want to go and change these header files. How can I solve this problem?

A temporary solution will replace

struct use_default;

to `boost / type_erasure / is_placeholder.hpp 'with



namespace iterators {
    struct use_default;
}
using iterators::use_default;

What's in `boost / iterator / iterator_adaptor.hpp '.
