FYI the isEmpty inline function was not meant to be widely adopted. I found it made a specific case more readable; the case where I had a huge number of interface functions returning const char *'s that might be null or empty. I then ended up using it throughout ws_workunits either for consistency or because I was changing massive amounts of code all at once.
