## *cltl1-in-package-compatibility-p*

If the value of this variable is true, in-package will work as it was specified in CLtL-1 rather than as it is specified in ANSI. That is, it will evaluate its required argument, it will accept the nicknames and use keyword arguments, and it will create a package if its required argument does not denote an already defined package. (ANSI calls for cl:defpackage to do what was done by in-package in CLtL-1.)

We provide this variable to allow you to use existing source files which depend on CLtL-1 in-package behavior but we recommend that you modify the files to use ANSI behavior as soon as possible. The initial value of this variable is `nil`.
