keep subpackges, delete root package

[bulk88]

I am trying to wipe a package of its local symbols, but not affect any sub packages under that package, to try to reload a module. The @ISA I noticed stays the same with Devel::Peek, so I put in the undef on @ISA. Are there any problems with this code which I dont see?

use strict;
use Data::Dumper;
use Devel::Peek;

BEGIN {
package p1::p2;
use vars qw|$VERSION @ISA $num2 |;
$VERSION = 0.02;
@ISA = qw( Exporter Inherit2);
$num2 = 2;
sub s2 { return 2;}

package p1;
use vars qw|$VERSION @ISA $num1 |;
$VERSION = 0.01;
@ISA = qw( Exporter Inherit1 );
sub s1 {return 1;}
$num1 = 1;
package main;
}

BEGIN{
    no strict 'refs';
    #print Dumper(\%{*p1::});
    undef(@{'p1::ISA'}); #magical
    foreach(keys %p1::){
        unless(length($_) > 2 && substr($_, -2, 2) eq '::'){
            delete ${p1::}{$_};
        }
    }
    #print Dumper(\%{*p1::});
}

Its not clear why you need to do this, so its hard to know if there are problems with the code
