Hi Christopher,
You are confusing/mixing two different issues, precisely the two issues
I'm
talking about in my two separate emails, but you mixed them here :)
I'd rather keep them well separated, because fixing the first should be
very
easy, it is a matter of agreeing (and a bit of work of course, adapting
the
test suite... I'm not saying it is zero work :)), where as fixing the
second, slot redefinition at subclass to follow the clos protocol,
represent
quite a lot of work, so it is not just a matter of agreeing...

As things are, both in 2.0 and 2.2, if you redefine a slot, it is a new slot,
nothing
is inherited (wrt to the slot I mean, methods are of course):
but this refers to my other email, let's keep the issues separated
> But why just setters and accessors? Why not also getters?
As I said above, When you do _not_ redefine the slot at subclass level,
everything
is inherited, except setters, hence my original bug report and this fresh email
which contains a much better explanation/situation description for Andy to
'play'
with ...

This refers to the other issue, and what clos does is in the summary of that
email,
as well as in the original bug report, which has links to further read ... of
course
the full protocol is in the spec
