NAME
Devel::Caller::Perl - Perl only implementation.SYNOPSIS
use Devel::Caller::Perl qw[called_args];
sub permute_args { my @args = @_; my @caller_args = called_args( 0 );

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_args [LEVEL]
"called_args" 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];
