I thought that @Douglas_Gregor had agreed to remove the restriction on using await in defer blocks. At least this is what he said:

So let's chalk this up to "we should remove this restriction unless more arguments come up in favor of keeping it."

SE-0296: async/await

I said it was contrived ;) Oh please no...that would be terrible UX. I believe conceptually a developer does not need to know that a try/throw/return statement might be a suspension point because the actual suspension point is in the defer block itself. The try/throw/return statement is control flow, and thus it results in jumping to some other place. That other place may happen to suspend, but that happens after the normal control flow. I agree that I wouldn't want this to force us to hav…

Was there a compelling reason to keep that restriction, or was this an oversight?
