> The inline `{@return}` tag is relatively new and will require developers to

> the inline version of `@return` "may only occur at the beginning of a

> When used like in the description of the issue, the tag technically belongs

> Since we don't have a method that returns the **complete** doc comment (yes,
> "getFullBody" is a bit of a misleading name), whose first element we could
> check against `{@return}`, I check `isEmpty()` before accessing the first

> Interestingly, `{@summary}` (must also appear first) lint is performed
> differently. However, I decided not to copy it since it operates on a lower
> level of abstraction: characters and strings thereof.
