While it is true that "undefined == null", this doesn't mean that "undefined"
and "null" are the same. For example, they give different results when
converted to string.

Looks like IE has a non-documented quirk when converting to what they call a
"variant" (see
- they treat undefined as null in this particular case. I'm not sure if it can
be expressed in IDL, CC'ing Sam Weinig to comment on this.
