I would prefer not to throw an exception. Making removeAttribute throw
an exception seems wrong since the attribute *is* in fact removed, and
making foo.multiple=false throw would mean that it would behave
differently from all other "mapped" IDL attributes.

I'd really prefer to keep things simple here as I doubt that this is
something that anyone will ever do. Much less depend on a particular
behavior.

You're off course free to put a warning in a developer console or
something like that though.
