Oh dear. I hadn't tested it very thoroughly - it works on g++ versions
2.95 and 3.3, but not 3.4 (which I guess you're using). I'm not sure
it's possible to deal with this on a compiler which implements two-phase
template instantiation, since the nullary function isn't a template
function. It might be best just to remove it, since I don't think it's
that useful anyway. Unless anyone's got a better idea.
