misleading errormessage #22

When a collection variable is given to a operation without expecting one, something like "1+2 + List", an exception is thrown:

System.Exception: PLUS operator can only be applied to numeric, string, date
at org.matheval.Operators.Binop.PlusOperator.Calculate(Object left, Object right, ExpressionContext dc)
at org.matheval.Expression.VisitNode(Node root)
at org.matheval.Expression.EvalT

The message is a little misleading, because the items in this list are either numeric, string or date.
Is it possible for you to change the error message to something more understandable?
