This is for post-monomorphization cycles. These are only caught later (in drop elaboration for the example that I saw), so we need to handle them here. This issue wasn't noticed before because exhaustiveness only checked inhabitedness when `exhaustive_patterns` was on. The preceding commit now check inhabitedness always, which revealed the problem. |
