Some low_hanging_fruit

[Zij-IT]

Saw your post on Reddit and just wanted to do a little bit to help out. Here are some random changes that were mostly inspired by my good friend clippy::pedantic!

None of these are behavioral changes, but just swapping some code with some other equivalent code.

I have locally merged/updated your fork branch with the latest changes.
@Zij-IT Can you give me write permission for your branch?

[Zij-IT]

If I am didn't mess it up you should now have write access to the fork!

I wasn't able to, sorry. Might be me, but this is the error when I tried git push zij-it HEAD:refactoring/low_hanging_fruit:

➜  swapvec git:(ede9f62) git push zij-it HEAD:refactoring/low_hanging_fruit
remote: Permission to Zij-IT/swapvec.git denied to Almeida-a.
fatal: unable to access 'https://github.com/Zij-IT/swapvec.git/': The requested URL returned error: 403

The codebase changed pretty much, so I am unsure how I feel about resolving the conflicts.
I also followed your advice and got some inspiration by clippy.
So maybe it makes sense to re-do the deltas where it makes sense and re-open this PR?
