Aha -- thank you Ondrej!

I had been wondering why I couldn't put the determinism of the higher  
order pred in the predicate declarations -- I'd expected to be able  
to say something like:

:- pred foo((pred(T::in) is nondet)::in) ...

Perhaps some more examples in the reference would be nice? (although  
I could have figured it out from 15.8.3 if I'd looked closely enough)
