I definitely prefer the ARRAY_CARDINALITY() instead of npos in my
version of the test. Beyond that, it looks like your test copied and
pasted so that the set vs. clear tests were independent, while mine
interleaved the two to traverse over the same set. Coverage wise,
either one of our tests gets just as much coverage of the added code; at
least, I didn't see anything added by your test8() that wasn't present
in my revised test4().

Anyone else have an opinion?
