Nod, could be my template metaprogramming that's at fault.... I can't help 
thinking that if I rolled my own ET's I could eliminate most of those by 
rolling the functionality directly into the operator overloads.... of course 
that may end up being even worse :-(

Anyhow I've filed a bug report on the ADL issue,

Thanks, John.
