I like it!  Maybe theStack can be made optional, too.  If so, should it
be defaultStack or topStack?
Anybody have ideas on specifying the card?

That depends on the application of this handler. Your choice :^)

But anyway, the buggyness was ours.
Though some more  elaborate elucidation on this kind of things
in the TD would not be a luxury.
A happy man greeting,
