+ * A function that returns the index of expr in (expr1, expr2, ...) list
or 0 if not found.
+ * It takes at least 2 parameters, and all parameters should be subtype of
AtomicType or NullType.
+ * It's also acceptable to give parameters of different types.
+ * If the search string is NULL, the return value is 0 because NULL fails
equality comparison with any value.
+ * When the paramters have different types, comparing will be done based
on type firstly,
