It would prevent an object from being implicitly converted.
I have a problem with instantiate a class within FunSpec because it would be implicitly converted. After it was implicitly converted, it had a lot of other extra fields, and now it couldn't be serialized.
One exception is: java.io.NotSerializableException: org.scalatest.verb.BehaveWord
Note: I was working on writing tests for a Storm job.
