应该怎么做才能让Rakudo(Star)不依赖于文件系统中的位置？

在perl5中,我曾经用'do(file)'来配置这样的配置文件:

---script.pl start ---
our @conf = ();
do '/path/some_conf_file';
...
foreach $item (@conf) {
    $item->{rules} ...
...
---script.pl end ---

---/path/some_conf_file start ---
# arbitrary code to 'fill' @conf
@conf = (
{name => 'gateway',
    rules => [
        {verdict => 'allow', srcnet => 'gw', dstnet => 'lan2'}
    ]
},

{name => 'lan <-> lan2',
    rules => [
        {srcnet => 'lan', dstnet => 'lan2',
         verdict => 'allow', dstip => '192.168.5.0/24'}
    ]
},
);
---/path/some_conf_file end ---

Larry Wall的"Programming Perl"也提到了这种方法:

但是FILE对读取程序配置文件等内容仍然有用.手动错误检查可以这样做: …

我想用Perl6/Rakudo编写我的程序,它必须在32位和64位操作系统(Windows和Linux)上运行.

但32位Rakudo安装程序将不再发布.

如何才能使用32位Rakudo Star安装程序？

我想使用STD.pm6从Perl 6解析Perl 6代码的最小工作示例
运行这样的东西

use v6;
use STD.pm6;
my $j = slurp 'e:\src\perl6\valid-p6-script.p6';
my $o = STD::Grammar.parse($j);
say $o.perl;

在调试器下给我绝对奇怪的输出:

e:\src\prg\perl6>c:\rakudo\bin\perl6-debug-m.bat -I. p6.p6
>>> LOADING p6.p6
>>> LOADING E:\src\prg\perl6\STD.pm6
