In the meeting notes you linked to, Waldemar (WH) noted that some of these variations may have grammar issues. Although not strictly ambiguous with conditional expressions, `fn ? ()` would require the use of YACG (yet another cover grammar). Also, what about computed property names? For example: `obj ? [Symbol.iterator]`. I'm not sure that even YACG will help here. (Thanks for compiling the list of previous threads BTW).
