NAME
   callee - support recursive anonymous functions

VERSION
   version 1.100820

SYNOPSIS
       use callee;

       my $f = sub {
           my $x = shift;
           return 1 if $x <= 1;
           $x * callee->($x-1);
       }->(5);

       # $f is 120

DESCRIPTION
   This module exports one function, "callee()", which allows anonymous
   functions to refer to themselves. This is necessary for recursive
   anonymous functions.

   A recursive function must be able to refer to itself. Typically, a
   function refers to itself by its name. However, an anonymous function
   does not have a name, and if there is no accessible variable referring
   to it, i.e. the function is not assigned to any variable, the function
   cannot refer to itself. This is where "callee" comes in.

   This module is just very thin syntactic sugar for Devel::Caller.

FUNCTIONS
 callee
   Returns a coderef to the function within which it is called.

SEE ALSO
   Takesako-san wrote "arguments.pm" - see
   <http://svn.coderepos.org/share/lang/perl/arguments/trunk/> - which does
   practically the same thing; see also his blog entry (in Japanese):
   <http://d.hatena.ne.jp/TAKESAKO/20080501/1209637452>.

   I released this module because "arguments.pm" is not on CPAN, and
   because Devel::Caller already existed on CPAN, but not with the syntax I
   wanted.

INSTALLATION
