What is an object?

[Jerzy Karczmarczuk <karczma@info.unicaen.fr>]

Dear Gurus,

Is there a way to extract from an instance of a class 
*all* its IVARs: names, and related values? 

Some kind of association table should exist somewhere.

I might consider looking into the implementation (object.c ??), 
but perhaps there is a hidden access to it directly from Scheme?

BTW. - this is a slightly related question, but independent, and
it isn't even a question...

The compiled, binary code of MrEd contains several dozens, perhaps
more than a hundred occurrences of the string "ivar/proc". I wonder
why...
