> The {{LiteralExpr.create()}} method “handles” the {{DATE}}, {{DATETIME}}, and {{TIMESTAMP}} class by returning a null value, with no exception. Change this to throw an exception so that calling code does not have to track down an NPE.
> That is, if literals of these types are not supported, then make this clear by throwing an {{UnsupportedOperationException}} or the like.
