SYNOPSIS

use Devel::Caller::Perl qw[called_with];

     sub permute_args {
       my @args = @;
       my @callerargs = called_with( 0 );
   
       my %caller_args =
         map { $ => $callerargs[$] } 0 .. $#callerargs;
   
       return \%caller_args;
     }

     sub dodad {
       my $args = permute_args;

       print $args->{0};
       # ...
     }

ABSTRACT

This module allows a method to get at arguments passed to subroutines higher up in the call stack.

DESCRIPTION
FUNCTIONS

called_with [LEVEL]

"called_with" returns the arguments to the subroutine at LEVEL in the call stack. If no level is specified, 0 (zero) is assumed, that being our caller. If a list is expected, it will be returned. When a scalar is expected, a list reference will be returned.

If you want the number of arguments passed to the subroutine at LEVEL, there's nothing stopping you from getting it from "caller".

my $number = (caller $level)[4];
