I *was* there, and that was a major contention between two groups. (I was on 
Ichbiah's side on this argument, but I didn't quit when I lost. ;-). I don't 
recall any technical objections that he had. The whole discussion 
degenerated into something rather theratical. I don't want to go into 
detail, because I don't want to speak ill of the dead (or of the living, for 
that matter).

I personally thought that using derived types (which no one understood in 
Ada 83) to implement classes was a mistake. Tucker was adamant on this 
point. I'm still not sure if he was right, but I'm used to it now. (Adding 
overriding indicators surely helps a lot, by indicating the programmers 
intent.)
