Sorry that it feels that way. My personal code also uses ()
overwhelmingly - so this isn't a personal agenda issue. I brought it
up because the person that wrote the code had chosen to use \, and as
far as I knew we didn't have a hard decision either way - and the
style guide we have talks preference not requirement, but the review
didn't distinguish between whether it's a suggestion or a requirement.
I'm seeking clarity so I can review more effectively and so that our
code doesn't end up consistent but hard to read.

Ok, thats interesting. Readability matters, and if most folk find that
even this case - which is pretty much the one case where I would argue
for \ - is still easier to read with (), then thats cool.

Totally not what I'm doing. I've been told that much of our style
guide was copied lock stock and barrel from some Google Python style
guide, so I can't tell what is consensus and what is 'what someone
copied down one day'. Particularly when there is no rationale included
against the point - its a black box and entirely opaque.
