I like the hash method combined with Params::Validate which nicely does what it says on the can and is great value for money. Give it a try ! 
use Params::Validate qw/:all/;

# MyModule->new(foo => 'val1', bar => 'val2')

sub new {
    my $class = shift;
    my %args = validate(@_, { foo => 1, bar => 0 }); # foo required; b
+ar optional
    ...
}
