Subject: New meta class sematics?

Hi,

with a cvs change on oct 24 ruby cannot create ``higher order''
 meta-classes anymore. That is assuming

class Object
    def meta(n= 1)
            if n == 0
               self
            else
              class << self; self end.meta(n-1)
           end
    end
end

# then

klass.meta(n) == klass.meta(1) # true

for all Class objects klass and n >= 1.  I agree that ``higher order''
meta classes made little sense but wouldn't it be simpler just to
raise an exception if one tries to create such classes?
To argue that a  meta-class is it's own meta-class seems odd to
me and was never (well, at least in the recent past) true until a
couple of days ago.
