Here is the code: (from the book "On Lisp", chapter 23)
  (setq cont #'identity)

SBCL complains:
  undefined variable: CONT

The variable "CONT" can't be defined here -- I mean, using "defvar" or
"defparameter", other macros depends on this undefined variable to do
some tricky things.
Is there a way to disable this warning? Then, any code using those
macros will not cause warnings?

In Visual C++, you can disable a specific type of warnings by:
#pragma warning(disable:4786)
Is there a similar method in Lisp?

Thanks.
