Line 108 is the static_cast< double >( pi ) for me. How can it compile | the three lines before but choke on 108?

Whatever will be standardizes shouldn't prevent | good code, but it's not responsible for bad compilers. But there should - | as I already said - be only one interface. Don't disagree with that but I see a 'chicken and egg' problem : until there is a Boost library file, nobody will use it, and there will be no pressure on compiler people to get a 'final solution' to work, and to work well.
