> There's an unused {{classTag}} {{val}} in the {{AtomicType}} base class which
> is causing unnecessary slowness in deserialization because it needs to grab
> ScalaReflectionLock and create a new runtime reflection mirror. Removing this
> unused code gives a small but measurable performance boost in SQL task
> deserialization.
