Named or positional arguments ?

both with Sub::Params

https://github.com/gooddata/perl-sub-params
just published on CPAN
issue learned: don't use unquoted V-string for $VERSION (thanks Andreas König)

    use Sub::Params;

    sub foo {
        my %args = Sub::Params::named_or_positional_arguments (
            args => \@_,
            names => [qw[ first second ]],
        );

        return $args{first} + $args{second};
    }

    say foo (1, 2);
    # 3
    say foo (first => 1, second => 2);
    # 3

Shared examples
