Perl 6 DBIish中断

Question

我已经将DBIish安装在我的macOS v10.13 (High塞拉利昂)上：

zef install DBIish

我的测试脚本是：

use v6;
use DBIish;

my $host='xxx.xx.xxx.xxx';
my $password='abc@123';


my $dbh = DBIish.connect('mysql', :host, :port(3306),
        :database<ald_xinen>, :user<aldwx>, :$password);

my $sth = $dbh.do(q:to/STATEMENT/);
    DROP TABLE IF EXISTS nom
    STATEMENT

$sth = $dbh.do(q:to/STATEMENT/);
    CREATE TABLE nom (
        name        varchar(4),
        description varchar(30),
        quantity    int,
        price       numeric(5,2)
    )
    STATEMENT

$sth.finish;
$dbh.dispose;

但当我运行它的时候，它得到了这个：

This type cannot unbox to a native string: P6opaque, Bool

我的Rakudo版本是：

This is Rakudo version 2017.09-361-g484f98725 built on MoarVM version 2017.09.1-575-gd4e230a6
implementing Perl 6.c.

那么，我如何让这个脚本工作呢？

您缺少要连接的主机参数上的$。
