1 Introduction

                                DEFREC
                                ------

                           By Robert Smith


DEFREC is a library for defining "top-level" mutually recursive
functions.

Example:

(defrec
  (even (x)
    (declare (type unsigned-byte x))
    (if (zerop x) t (odd (1- x))))
  (odd (x) 
    (declare (type unsigned-byte x))
    (if (zerop x) nil (even (1- x)))))

Now we can call EVEN and ODD.

5 Definitions

Definitions are sorted by export status, category, package, and then by lexicographic order.

5.1 Exported definitions

5.1.1 Macros

Macro: defrec &body DEFINITIONS

Define mutually recursive functions. Each definition of DEFINITIONS should be of the same form of FLET or LABELS:

(<function name> <lambda list>
<function body>).

Currently, lambda lists can only be lists of symbols. &REST, &OPTIONAL, and &KEY arguments are not supported.
