Hm, that would require some code duplications since you want this counter
to behave similarly like Fixnum+ which means the type of the internal
value vepresentation must be changeable etc.  I find this quite ugly and I
don't know whether the performance improvement would justify this
ugliness.

Until now I've seen cleanness and simpleness as one of the core features
of ruby that I would not want to see easily sacrificed.  If this solution
would proove significant more efficient than the current I guess best
would be to provide it as an add on module.
