By retronym:

In 2.8 vintage compilers, the subtle difference in the types `TC[A]` (as you get with a type annotated val) vs `AnyRef with TC[A]` (with an object) used to foil implicit search in a few cases. It's a new year, and we've got a new compiler, but the old problems resurface in new ways: this time the SBT API signature of the objects isn't stable, resulting in transitive recompiles each time I touched Stream.scala.

Here's the bug I lodged: https://github.com/harrah/xsbt/issues/288
