Isn't the point of this discussion that it is already gone?

Nobody has even suggested removing tuple-unpacking in general.

The question is whether to continue doing it implicitly in function parameters.

Today, you can write:

>>> def f(name, (street_num, street, city, state, zip)):

In python 3, you will probably have to write:

>>> def f(name, addr):
...         street_num, street, city, state, zip = addr

or possibly the redundant

>>> def f(name, addr:tuple(street_num, street, city, state, zip)):
...         street_num, street, city, state, zip = addr

if you want the documentation value.
