I had no idea that "str()" or "int()" would do that.  "file()" certainly
doesn't! :)

I don't really think there's much reason to make "iter()" work.  As you say,
"iter([])" works just fine.  For those rare times you want an empty iterator, I
don't think the two extra characters is much of a price to pay.
