fix workaround false positive clippy lint `reversed_empty_ranges`

[ModProg]

As the rust-clippy issue https://github.com/rust-lang/rust-clippy/issues/5808 doesn't seam to make much progress I propose to just allow the lint for s![] macro invocations for now.

The let = ... is necessary, because attributes are not allowed on expressions currently (https://github.com/rust-lang/rust/issues/15701).

@bluss removed the depricated zip

[bluss]

Can we hold off on removing the deprecated zip until it can be replaced by std::iter::zip? That's after all the whole point of it, to use the function version :slightly_smiling_face:

(Function zip is the best :slightly_smiling_face: )

[ModProg]

Yeah no problem, only did so because the ci was failing because of it.
