*handle-old-in-package* Variable


Controls the handling of CLtL1-style in-package forms.



Initial Value



The variable *handle-old-in-package* controls what happens when a CLtL1-style in-package form is processed. This refers to the specification in Common Lisp the Language, first Edition, which preceded ANSI Common Lisp and specified in-package as a function with keyword arguments.

The allowed values are as follows:

Quietly use the CLtL1 definition of the in-package function.
Signal a warning and use the old definition.
Signal a continuable error.
