maybe a non-dummy widget could not have the parent attr,  that depends on the
context.

DummyWidget is a rather implicit mechanism that let write natural code as long
as one knows what behind the scene is allowing for that. OTOH is copy-&-past
and random code inspection unfriendly. Checking for exceptions that it should
avoid make things even more obscure.

Either it is used at its "maximal potential" and very prominently documented,
or a more explicit way is better, given how anygui
grows (want to implement this in backend B, check how backend A does it).
