I agree with both of you. If the decorator decorates the class, it should
be after `export`, not before. I'm sorry if that means that there is a
bunch of code written with earlier Stage 1- and Stage 2- versions of
decorators that did it the other way, but that's not nearly a good enough
reason (IMHO) to do something so clearly non-intuitive and that breaks
parallel construction. RIght now, you say "If you want to export X, you put
`export` in front of it" (in the simple case). Breaking that for decorated
classes seems like a horrible idea.
TC39 is meeting this week. Here's hoping they come to resolution on this
stuff and, as is usually the case, a good one that makes sense.
