LGTM. Thank you!

@Philippus How would you like to see this published? We could cut a 2.1.1 across supported versions of Scala, or we could silently roll this functionality in the 2.1.0 release starting from Scala 2.12.2.

[Philippus]

To me it doesn't sound like a huge problem that warrants a separate release, so I would say put it in the 2.1.0 release. Or does this mean that it will only be fixed for Scala 2.12.2?

[Philippus]

it doesn't look like this was published yet? And we are at the 2.1.0 release.

[xeno-by]

What version of Scala are you using?

[Philippus]

Let's add it to 2.12.2 ?

[xeno-by]

Looks like I didn't cherry-pick this commit to the branches supporting recent versions of Scala. Neither 2.11.11, nor 2.12.2 releases of paradise have this logic :(

I suggest we cut a 2.1.1 release. What do you think?

[Philippus]

Sounds good to me!
