There was a problem hiding this comment.
Alternatively we could position the error on =>:
If the span highlights the return type, it might suggest an issue with the return type rather than the returned value/expression. => on the other hand would suggest it could be an issue with either the return type or the value. This would be synonymous to the behaviour with block body arrow functions where we highlight the return keyboard.
However, the error might be harder to see, because => is only 2 characters. I would personally be fine with this.
