So @implVersion is an entirely different variable to
@@implVersion.

In Net/HTTP @implVersion is only assigned in one
place:

    def HTTP.setimplversion( obj )
      f = @@newimpl
      obj.instance_eval { @newimpl = f }
    end

I cannot find anywhere in the code that is calling
.setimplversion, yet changing the declaration of
@@newimpl is reflected in @newimpl.

Could anybody explain how this is working?
