What use is there for 'ends' these days?

Question

I came across a subtle bug a couple of days ago where the code looked something like this:

ostringstream ss;
int anInt( 7 );

ss << anInt << \"HA

There are some APIs that expect a "string array" with multiple zero terminated strings, a double zero to mark the end. Raymond Chang just recently blogged about it, most of all to demonstrate how often that this gets fumbled.
