将 MooseX::Method::Signatures 导入调用者的范围
我制作了一个“捆绑”模块，它可以做很多事情：导入 Moose、导入 true、namespace::autoclean，使调用者的类不可变（取自MooseX::AutoImmute）。我无法弄清楚的一件事是如何包含 MooseX::Method::Signatures。
这是我到目前为止所得到的：
package My::OO;
use Moose::Exporter;
use Hook::AfterRuntime;
use Moose ();
use true ();
use namespace::autoclean ();
my ($import, $unimport, $init_meta) = Moose::Exporter->build_import_methods(
also => ['Moose'],
);
sub import {
true->import();
my $caller = scalar caller;
after_runtime { $caller->meta->make_immutable };
namespace::autoclean->import(-cleanee => $caller);
goto &$import;
}
sub unimport {
goto &$unimport;
}
1;
想法是，在我的代码中，我现在可以做这样的事情：
package My::Class; {
use My::OO;
extends 'My::Parent';
method foo() { ... }
}
但现在我仍然必须包含一个额外的 use MooseX::Method::Signatures;。如何将其包含到我的 OO 模块中？
I've made a "bundle" module which does a bunch of things: imports Moose, imports true, namespace::autoclean, makes the caller's class immutable (taken from MooseX::AutoImmute). The one thing I haven't been able to figure out is how to include MooseX::Method::Signatures.
Here's what I've got so far:
package My::OO;
use Moose::Exporter;
use Hook::AfterRuntime;
use Moose ();
use true ();
use namespace::autoclean ();
my ($import, $unimport, $init_meta) = Moose::Exporter->build_import_methods(
also => ['Moose'],
);
sub import {
true->import();
my $caller = scalar caller;
after_runtime { $caller->meta->make_immutable };
namespace::autoclean->import(-cleanee => $caller);
goto &$import;
}
sub unimport {
goto &$unimport;
}
1;
The idea is that in my code, I can now do things like this:
package My::Class; {
use My::OO;
extends 'My::Parent';
method foo() { ... }
}
but right now I still have to include an extra use MooseX::Method::Signatures;. How can I include that into my OO module?

首先，请注意
Hook::AfterRuntime的实现非常脆弱。虽然它适用于许多简单的事情，但很容易导致难以调试的错误。我建议您自己编写->meta->make_immutable，或者使用其他方法来绕过编写它，例如MooseX::Declare。回答您的实际问题：
First off, please note that the implementation of
Hook::AfterRuntimeis quite fragile. While it works for many simple things, it's extremely easy to end up with very hard to debug errors. I'd recommend just writing the->meta->make_immutableyourself, or using other approaches to get around writing it, likeMooseX::Declare, for example.To answer your actual question:
