I thought the problem was that each() will return a fresh array each time
because of foo(). each() always adds to the array foo() returns.
I also thought a better solution would be to use a foreach lop instead of
while.
foreach (foo() as $key) {
echo "dummy";
}

It's a bug alright--yours. foo() will return a fresh array each time,
so the condition is always true.
