I have a case where we'd like to overload a dictionary argument with a
callback argument (why is a long story).

But the table at http://heycam.github.io/webidl/#idl-overloading says
that dictionary, callback functions and objects aren't distinguishable
from each other.

Can someone point me to an explanation of why?
