Comment (by goldfire):

 Replying to [comment:3 bgamari]:
 > I am a bit confused; the cited example appears to compile for me with
 7.8, 7.10.1, and 7.10.2. Perhaps this was introduced since 7.10 branched
 from master?

 Quite possible. I guess I didn't test in 7.10. And, in any case, you've
 simply decided that it's not convenient to merge the change. :)
