I recently made a foolish mistake while assigning a variable. I had intended to write
> var RUNTIME = "runtime";

but instead I wrote:
> var RUNTIME = RUNTIME;   // RUNTIME is now `undefined`


I can't think of a valid usecase for assigning the same variable to itself. It would be nice if the validator flagged this as a potential error.

Upstream eslint doesn't seem to have this feature, so it might be worth contributing back.
