There will be more than one - at least three - distinguished by size - I can 
tell from the count attributes which class has these ARRAY [BOOLEAN]. So it 
would be nice to skip that level of referer, and go directo the the next 
class up in the hierarchy (the culprit class will be at least 3 levels 
higher up, so I'd rather skip as much work as possible). Is there a way to 
get the INTEGER key from the class name?

Whether or not, having clioned the SPECIAL [ANY], how do I compare the two 
to find the new ones? Are they sorted by age, so I will see the new ones at 
the end of the list, or is there some other way of telling which is new (the 
list of SPECIAL [BOOLEAN] has a count in the hundreds, many of which will be 
legitimate).

We have built internal tools for EiffelStudio for doing this kind of stuff. If
you want to play with them, send me a private email and I'll give you some more
instructions.

I'm not sure what you mean here.

There is no facility on SPECIAL, so you will need to perform as many linear
traversal as needed to find the new items between the old SPECIAL [ANY] and the
new one.
