May I encourage you to make trivial style corrections when you
touch a piece of code anyway (here: add a missing blank line
ahead of the line you change). It's fine to restrict this to just
code you actually change, i.e. it's generally preferable if you
don't change lines you don't touch anyway.

Same here then (pointless cast could be dropped).

Whereas this is an example where I personally wouldn't drop the
cast, but I'd consider combining the last two lines.

Pointless cast should be dropped again.
With these adjustments
