$Revision: 5.0.2.5 $
Package: EXCL
This variable holds an alist associating special variable symbols with forms to evaluate for binding values. When a process first starts execution its initial-bindings slot is examined for bindings to establish on the process' stack-group. *cl-default-special-bindings* contains a reasonable default list which establishes a default environment with standard Common Lisp values. The contents of this list may be examined, but if you want to modify it for a particular call to mp:make-process, it is strongly suggested you either modify a copy made with copy-alist, or just cons replacement entries onto the front of the list.
Samples of the contents of *cl-default-special-bindings* are shown in the table below. For all Lisp-package variables the initial value will be the same as the standard Common Lisp default.
