Well, assume that str could be "goodby". Say it (and i) comes from
somewhere else. the result would be:
str i output
hello 1 "bar\n"
hello !1 error: no default
goodby any "foo\nbar\n"
It's all moot because it doesn't work and, IMHO, goes along with the
duff's device into the category of "things that you probably shouldn't do".
