My crystal ball tells me that there's a lot more code going on here
than you've shared with us, and suggests that maybe you had a few
tries at this. If you instantiate an object from a "class TableauNoir"
and then redefine that class, the object is still of the old class,
even though the classes have the same name. You'd need to construct a
new object of the new class.
