Actually, that is not the case. If you take phoenix, bind or lambda,
and call the resulting functor with not enough arguments it will give
you a pretty ugly error.
And this is what the currying is about ... return another functional
if the supplied arguments aren't enough to evaluate the lazy function
object.
What you mean is you supply too much arguments. Which won't be affected.
