It turns out that I didn't have the flu and I didn't get it from the ARG 
meeting or most likely the associated travel. After 11 days in the hospital 
and following recovery, I'm now just getting back to (some) work.

That's probably not implemented exactly as described by the AI/future 
Standard, since we just finished work on it a few days before the date of 
this message. Also, experience shows that these early implementations are 
often full of bugs (usually, the first few ACATS tests for a feature show 
*lots* of problems). So I wouldn't depend too much on those features yet - 
they'll probably change some before being "right".
