That would be useful. Also would be useful if, instead of just printing "no such object" when there isn't one, there could be some sort of bang to indicate this, so that object can be created if necessary.
who is in charge about coordinating tcl/tk and pd? only Mr. Puckette? I guess that an option to query objects for their parameters would really speed up and enhance interface design in pd. something like "; myhslider get_width". currently it can only be used to get the coordinates of a canvas.
