-----------------------------------
navis has commented on the revision "HIVE-4025 [jira] Add reflect UDF for
member method invocation of column".
I've thought the name like "reflect_instance" or something, but found current
"reflect" can invoke method of instance also(by calling default constructor of
target class).
Naming is hard. How about "type_reflect"?

> There are many useful non-static methods on type of primitive types. But
> current reflect UDF cannot invoke those. For example,
> select reflect2(value, "replace", "val", "VALUE") from src;
> which replaces 'val' part of value column with 'VALUE'
