def deep(): collection.IndexedSeq[Any]

@lrytz Do you know if there was a reason to not have it in Array anymore? I see that you added it to partest tools only in scala/scala@977df0c.

[lrytz]

It's a hacky ugly testing utility to print values in (nested) arrays. If you feel strongly about it, we can add it deprecated.

Yes I think we should leave it: scalatest/scalatest#1383
