Here's some code that you may find useful. You need to take into account one of the previous comments that this is only a snapshot, but it should help you. 
#!/usr/bin/perl

use strict;

sub sub1 {
    print "In sub1\n";
}

sub sub2 {
    print "In sub2\n";
}

sub sub3 {
    print "In sub3\n";
}

sub MergeHashes {
    my ($hr1, $hr2) = @_;
    my (%retval, $nkey, $key);

    print "hr1 = $hr1, hr2 = $hr2\n";
    foreach $key (keys %{$hr2}){
    $retval{$key} = $$hr2{$key};
    }

    foreach $key (keys %$hr1){
    if (!defined($retval{$key})){
        $retval{$key} = $$hr1{$key};
    }
    }
    
    \%retval;
}

sub showhash {
    my ($hr, $hn) = @_;
    my %hash = %$hr;
    my @subs;

    no strict;

    return if ($checked{$hr});
    $checked{$hr} = 1;
    my $symname;
    foreach $symname (sort keys %hash){
    local *sym = $hash{$symname};


    if (@sym){
        push(@subs, "array $symname");
    } elsif (%sym){
        push(@subs, "hash $symname");
        showhash(\%sym, $symname);
    } elsif (defined(&sym)){
        push(@subs, "sub $symname");
    } else {
        push(@subs, "var $symname");
    }

    }
    if (scalar @subs){
    print "Package $hn => ";
    foreach $symname (sort @subs){
        print "\t", $symname, "\n";
    }
    }
}

my %hash = (
        h1 => {
        a => "A",
        c => "C",
        e => "E",
        g => undef,
        i => undef,
        },

        h2 => {
        a => "A2",
        b => "B",
        d => "D",
        g => "G2",
        h => undef,
        }
        );

showhash(\%main::, "%main::");
