That would be rather too loose for my tastes. A mapping
can be *represented* as a set of tuples, but that's not
the same thing as it *being* a set of tuples.

I think to most people it seems like a solution
looking for a problem. In all the code I've ever
written, plain duck typing has been perfectly
adequate. I'm willing to concede that it might
have use in some specialised areas such as Zope,
but there doesn't seem to be any general demand
for it.
