There's no GLR issue if we do what we're doing for assignment expressions, including destructuring: parse a cover grammar into a reference-tree. I'm drafting that to see how it works in the existing spec.
Lots of languages and notations use arrow in between parameters and body. We should not deviate from that and uglify things lightly. I don't see good reason yet.
