I appreciate the Odersky PR that says "we need a better solution". This is such a PR, if only it had a PR label. |

There was a problem hiding this comment.
This is kind of weird since dealias does skip aliasing bounds. It would be good to get an explanation what exactly goes wrong here. What's the type of target0.dealiasKeepOpaques in the failing test? What is its info? Is there an opaque type involved?
