4136,"Boost.Range : put ""using namespace boost::adaptors"" creates conflict.",thomas.petit33@…,Neil Groves,"Hi,[[BR]]

With the current version on the trunk, I get compilation errors with the following program (MSCV10 RC1).


{{{
#include <boost/range/adaptors.hpp>
using namespace boost::adaptors;

int main()
{
}
}}}


Message error : ""1>F:\Program Files\boost\boost/range/iterator.hpp(63): error C2039: 'type' : is not a member of 'boost::mpl::eval_if_c<C,F1,F2>'""
...

See [1] to get the full message error.

I narrowed down the problem to the three adaptors ""copied, sliced and tokenized"". See below :

{{{
// Uncomment one the three adaptors below to get the same compilation error
// #include <boost/range/adaptor/copied.hpp>
// #include <boost/range/adaptor/sliced.hpp>
// #include <boost/range/adaptor/tokenized.hpp>

// these one are fine
#include <boost/range/adaptor/adjacent_filtered.hpp>
#include <boost/range/adaptor/filtered.hpp>
#include <boost/range/adaptor/indexed.hpp>
#include <boost/range/adaptor/indirected.hpp>
#include <boost/range/adaptor/map.hpp>
#include <boost/range/adaptor/replaced.hpp>
#include <boost/range/adaptor/replaced_if.hpp>
#include <boost/range/adaptor/reversed.hpp>
#include <boost/range/adaptor/strided.hpp>
#include <boost/range/adaptor/transformed.hpp>
#include <boost/range/adaptor/uniqued.hpp>

using namespace boost::adaptors;

int main()
{
}
