Aha, I think this is the key. I was thinking that even though the Closure
overload selection was temporarily disoriented, explicitly providing an
argument list might be sufficient help to constrain the overload. This makes
the situation clearer. That said, while smoother resolution would be more
_convenient_, I filed this ticket because of the non-localized and confusing
internal error message.
