mysql - Perl 6 DBIish 坏了

Question

我已经在我的 macOS v10.13 (High Sierra) 上安装了 DBIish:

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;

但是当我运行它时，它得到了这个:

This type cannot unbox to a native string: P6opaque, Bool
  in block  at /Users/ohmycloud/.rakudobrew/moar-nom/install/share/perl6/site/sources/F2D45FC1BC0A15B4C8511E3A864F1FC1C3F269BB (DBIish) line 41

我的乐道版本是:

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

那么，我该如何让这个脚本工作呢？

您缺少要连接的主机参数上的 $。
