object TryFailed extends WartTraverser

Wart such that we avoid using Try.failed

Using Try.failed seems to be a bad idea because it will create an UnsupportedOperationException for each Success, which constantly builds a stack trace and then throws it away. Seems to be quite expensive in particular in tight loops.

Better match on a Try. If you need failed.foreach, use TryUtil.forFailed instead.
