> There are a number of places in the code that are missing default branches on case statements.
One particular instance I noticed is in OptionValue.createOption, which returns null if passed
an unexpected type. This and a few other places in the code could be made a little nicer to
work with if we just provided the standard behavior of throwing an exception.
> One additional note, in a number of places where we do have defaults, but the exception
thrown is an UnsupportedOperationException with no message. DRILL-2680 discusses this problem,
so this might be handled over there, but as we fill in the switch defaults we should try to
avoid introducing the new problem of exceptions lacking descriptions.
