LispWorks Delivery User Guide > 5 Keywords to the Delivery Function > 5.2 Alphabetical list of deliver keywords




Default value: t

When this is non-nil, all functions deleted by the treeshaker are replaced by small stub functions. When a deleted function is called by the application, its stub prints a message telling you that the function has been deleted and how it can be reinstated. These stubs can take up a lot of space if you smash large packages, but are invaluable while refining delivery parameters.

For instance, if your application calls complexp after delivery with :keep-complex-numbers set to nil , a message like the following is printed:

Attempt to invoke function COMPLEXP on arguments (10).
  COMPLEXP was removed by Delivery keyword :KEEP-COMPLEX-NUMBERS
