BTW, I actually have a use for redefining a pendent function.

The package manager may unload itself by ⎕ex-ing all of its names. It
does this, of course, while the main package manager function is
pendent.

If that's all I did, then the main function would be missing when I
called the ]pkg user command. Rather than complicating that main
function to figure out what else may or may not be loaded, I define a
new version of the function that simply prints a message.

Here's a transcript:

      )load pkg
loading )DUMP file /home/dlamkins/workspaces/pkg.apl...
    User-defined command ]pkg installed.
      ]pkg
 Commands:    help     [command]     
              ident                  
              packages               
              depends  package-name  
              metadata package-name  
              load     package-name  
              unload   package-name  
              new      package-name  
              rescan                 
              names    prefix        
      ]pkg unload apl-packager
 The package manager is now unloaded. 
      ]pkg
 The package manager is unloaded. 
 `)load pkg` reloads the package manager.
