[boost] using lexical_cast with tuples.

Hello,

  I'm guessing this has something to do with the unsetf(std::ios::skipws)
call. Anyway, the following code seems contradictory since it's output is
"Exception Thrown".  Has anyone else come across this?

#include <iostream>
#include <boost/tuple/tuple.hpp>
#include <boost/tuple/tuple_io.hpp>
#include <boost/lexical_cast.hpp>

int main()
{
    boost::tuple<float,float> aTuple(2.2f,3.3f);
    std::string theString = boost::lexical_cast<std::string>(aTuple);
    try
    {
        boost::tuple<float,float> i = 
            boost::lexical_cast<boost::tuple<float,float> > ( theString );
    }
    catch(...)
    {
        std::cout << "Exception Thrown" << std::endl;
    }
}

Thanks,
