Converts a Stopper to a function type that prior to the ScalaTest 1.
Converts a Stopper to a function type that prior to the ScalaTest 1.5 release the
Stopper extended.
Prior to ScalaTest 1.5, Stopper extended function type () => Boolean.
This inheritance relationship was severed in 1.5 to make it possible to implement Stoppers in Java, a request by an IDE
vendor to isolate their ScalaTest integration from binary incompatibility between different Scala/ScalaTest releases.
To make a trait easily implementable in Java, it needs to have no concrete methods. Stopper itself does not declare
any concrete methods, but () => Boolean does.
This implicit conversion was added in ScalaTest 1.5 to avoid breaking any source code that was actually using
Stopper as an () => Boolean function. It is unlikely anyone was actually doing that, but if you were
and now get the deprecation warning, please email scalatest-users@googlegroups.com if you believe this implicit conversion should
be retained. If no one steps forward with a compelling justification, it will be removed in a future version of ScalaTest.
