Perhaps I need to look very closely at ILE again.  Last time I looked, it didn't
co-exist too well with OPM: the interaction between named activation groups
and the default activation group left something to be desired.  Also, lack of
MAKE and documentation tools.  

There was the sense here that ILE was too little, too late (but that doesn't 
mean much).  The biggest hurdle here was teaching OO design
methodology to people who've never heard of it.  "Too much learning
curve" was what I kept hearing...  Is that just a rumour?
