I've tried converting the TR1 lib to use that implementation but I'm having
trouble with the std::pair interface which appears not to work:

tuple_size<std::pair<int, long> > doesn't have a data member "value"

BOOST_STATIC_ASSERT((::boost::is_same< ::std::tr1::tuple_element<1,
std::pair<int, long> >::type, long>::value));

Fails, I'm not sure what type tuple_element is reporting though.

Finally the "get" function appears not to work with pairs.

BTW is this implmentation documented anywhere?

Regards, John.
