Also, see the style guide for bracing: https://llvm.org/docs/CodingStandards.html#don-t-use-braces-on-simple-single-statement-bodies-of-if-else-loop-statements

Everyone struggles w/ that one, since we dont' have the clang-format set for it by default.

I'm also not sure that using an object key is a great solution to wrapping. Did you consider other alternatives?
