	As Glynn had already pointed out, it isn't.

	But note that there's no `variable array VARN' form.  I guess,
	the intended effect could be achieved by something like:

   variable  VARN
   array set VARN { }

	Or, introducing a new procedure:

proc var-array { varn } {
    uplevel 1 [ list variable  $varn ]
    uplevel 1 [ list array set $varn { } ]
}

...

   var-array VARN
