📎 Port `arrow-body-style` from eslint

[dyc3]

Description

Port the arrow-body-style rule from eslint.

Suggested names:

• useConsistentArrowReturn

The eslint rule has options, but we don't usually implement options on the first iteration of a rule. For this task, implement the functionality that is equivalent to the default option (which would be as-needed).

Hey @dyc3 I would like to take this issue! 😀

Is there another task for the "always" eslint setting (i.e., requiring you to add explicit block and return statement)? If not, it would be nice if the title of this were revised to: Port arrow-body-style: as-needed from eslint.

We could use a name such as useConsistentArrowReturn. I think that name works even if we add the option.

I like that, and it seems to align with other rules that let you pick a potentially controversial style and enforce it, e.g., useConsistentArrayType

@isjavierdiaz it's been 5 months. I assume you don't have time.
