> Various user-defined objects can be created which are bound to Java methods or classes
via "external name" clauses. It's easy to mis-phrase the Java class name in the "external
name" clause if the class is a static nested class. The affected objects include:
> o Functions
> o Procedures
> o Types
> o Aggregates
> Consider the following class:
> public class TestFuncs
> {
>     public static final class Foo
>     {
>         public static double    pow( double base, double power ) { return Math.pow( base,
power ); }
>     }
> }
> If the pow method is bound to a user-defined function via a CREATE FUNCTION command,
its external name should be TestFuncs$Foo.pow, NOT TestFuncs.Foo.pow.
> We should add a section to the Reference Manual clarifying how to phrase the external
name if it includes a reference to a static nested class. The detailed sections for the various
user-defined objects can then refer to this new section.
