Maybe you just want something like this;

package Foo;

sub new {
  my $pkg = shift;
  my %self = @_;
  my $self = bless \%self, $pkg;
  # do stuff to $self (now a __PACKAGE__)
  return $self;
}

1;

Then,

use Data::Dumper ();

my $foo = Foo->new(a => 1, b => 2, c => [qw/apple banana grape/]);

print Data::Dumper::Dumper(\$foo)
[download]

Output:

$VAR1 = \bless( {
                   'b' => 2,
                   'c' => [
                            'apple',
                            'banana',
                            'grape'
                          ],
                   'a' => 1
                 }, 'Foo' );

If you want the basis for a Foo to be an array ref, then,

package Foo;

sub new {
  my $pkg = shift;
  my @self = @_;
  my $self = bless \@self, $pkg;
  # do stuff to $self (now a __PACKAGE__)
  return $self;
}

1;
[download]

Output:

$VAR1 = \bless( [
                   'a',
                   1,
                   'b',
                   2,
                   'c',
                   [
                     'apple',
                     'banana',
                     'grape'
                   ]
                 ], 'Foo' );

Note, => is taken as a comma when an array is on the LHS of the assignment (=). Hashes can be treated as even-sized arrays - or arrays of tuples (i.e., key => val).
