No I didn’t think about or consider it. I agree with you that this seems like it would be consistent with the rest of the language and can use the same mechanics we use for disambiguating two expressions on consecutive lines in a brace statement. It also seems like it would lead to more pretty code in general as well.

I agree that this could be positioned as a subsequent additional proposal. I’d personally be fine with looping this into the original proposal, but I’m also happy to split it out if you'd prefer Erica,
