It's unclear to me what you really want. For now, I'll assume you want multiple inheritance. Here's how I would do it (but there are more ways to do it than there are Perl programmers)

#### Foobar.pm #####
package Foobar;

use Foo;
use Bar;

our @ISA = qw[Foo Bar];

sub new {bless {}, shift}
sub init {
    my $self = shift;
    my %args = @_;
    $self->Foo::init(name => $args{name})
         ->Bar::init(age => $args{age});
    $self;
}

1;
#### Foo.pm ####
package Foo;

sub new {bless {}, shift}
sub init {
    my $self = shift;
    my %args = @_;
    $self->{name} = $args{name};
    $self;
}
sub name {$_[0]{name}}
1;

#### Bar.pm ####
package Bar;

sub new {bless {}, shift}
sub init {
    my $self = shift;
    my %args = @_;
    $self->{age} = $args{age};
    $self;
}
sub age {$_[0]{age}}
1;
#### foobar.pl ####
use Foobar;
my $o = Foobar->new->init(name => 'Tom', age => 23);
