Yes, see e.g. Params::Validate
update
An example: 
#!/usr/bin/perl 
use strict;
use warnings;
use v5.10;
package Player;
use Params::Validate qw(:all);

sub new {
    my $class = shift;
    my %attr  = validate(@_, {name => 1, race => 1});
    return bless \%attr => $class;
}

package main;

my $player  = Player->new(race => 'Elf', name => 'Legolas');

# dies: missing attribute
my $player2 = Player->new(race => 'Dwarf');

# dies: unknown attribute
my $player3 = Player->new(race => 'Hobbit', name => 'Bilbo Baggins', s
+ize => 'small');

say 'done';
