Thanks, @xuwei-k. There are at least a couple of other places where we have workarounds for 2.10—maybe it's time for version-specific source trees.

Note that Scala.js currently does not look into shared/src/main/scala-$VERSION directories (see scala-js/scala-js#2005) so you would have to duplicate some files across js and jvm directories.

Sorry for kind of barging in (saw @travisbrown 's tweet), but wouldn't making the field private (class FooOps(private val a: A) extends AnyVal etc.) be a viable fourth solution? It does seem to properly hide the a method.

@chwthewke That works on 2.11, but not 2.10, unfortunately.

@travisbrown Gotcha, thanks for the explanation

I don't think option 2 is a bad choice. It would be consistent with the common approach of giving implicit values long, descriptive names to avoid likely clashes.

Note that Scala.js currently does not look into shared/src/main/scala-$VERSION dir....
