Yes, technically speaking, you're correct. 

But the concept of "code smell" has become something of a
scarlet letter within the programming community. Once you
apply it to someone's code, the stigma becomes very
difficult to rub off -- and not just the "external" stigma
you feel radiating from scornful stares of your peers, but
the "self-imposed" stigma as well. It has become a
derogatory term, and sadly, one that is thrown around much
too carelessly.

Sure, there are legitimate instances where the term should
be applied, but in the case of "zip vs explicit sequence
indexing", the usage of this term could influence a "less
experienced Python programmer", to adopt a very dangerous
habit *SIMPLY* because he does not want to be labeled a "bad
programmer". But the irony is, he may produce worse code by
blindly reaching for his "sequence zipper"!

The zip function is not something you should get in the
habit of using without first considering the consequences of
*EACH SPECIFIC USE-CASE*. Yes, it can be helpful at times,
and yes, it can make code easier to read. But it can also
create subtle bugs. Personally, i choose to avoid it, but
others should make the decision for themselves.

In a nutshell, the zip function is both "elegantly powerful"
and "cunningly destructive". So buyer beware. Because,
Python.org ain't no Walmart folks, and they sure as hell
don't give refunds for sequence members that evaporated into
the ether, after you adopted the bad habit of using zip,
simply because -> "Mark said so"!
