Dear Booster's
Booster's what?
...
I have a problem compiling a tuple containing an enum in a
namespace. For example:
namespace TestTuple
{
    enum ETestTuple
    {
        eTestTuple0 = 0,
        eTestTuple1 = 1
    };
}
void Testtuple5()
{
    typedef boost::tupleTestTuple::ETestTuple Tuple;
    Tuple tpl;
}
does not compile. I am using MSVC 2003.net (7.1 version), 
just native code. Is this a M$ problem or is tuple broken?
Looks like a compiler bug to me.
...
Also I get problem with 
the combination 
of boost::bind and tuple, for example:
int               i;
boost::tuple<int> data;
i = data.get<0>();                                  //ok
i = boost::tuples::get<0>(data);                    //ok    
i = boost::bind(&boost::tuples::get<0>, _1)(data);  //error
Has anyone a clue?
boost::tuples::get has three template parameters - index, head type
and tail type.  Usually the type arguments can be deduced, but since
you're passing the address to another template function you need to
specify all three arguments.
...
Btw searching lists.boost.org is very hard, because google 
is out of sync with the list.
Try http://news.gmane.org/index.php?prefix=gmane.comp.lib.boost
instead.
