not everything. there are some things that are objectively good, such as `fn
name(args...) -> ReturnType` because you can grep "fn some_name" and you know
you find a function. if you want to find a function that returns `FooType` you
grep "-> FooType"

There are some caveates and constraints to say that such decisions are
"objectively good", similar to when you say "deep nesting/indentation is
objectively bad"

e.g. "I don't like implicit setting of variables" is kinda vibey, but when you
give the caveat "in projects that are at scale, with many people working on
them, and lots of movement, having variables with values that are set implicitly
is objectively bad due to the risk of difficult to detect unexpected behavior",
there is a reasonable degree of objective truth to it.
