[Catalyst] OT Config::General question

[Jesse Sheidlower]

I want to set up my new PageCache configuration in a
Config::General style. I need to change this:

__PACKAGE__->config(
      'Plugin::PageCache' => {
          expires => 300,
          set_http_headers => 1,
          auto_cache => [ '^(search)' ]
          debug => 1,

        }
);

into this:

<Plugin::PageCache>
	expires 3600
	set_http_headers 1
	auto_cache [ '^(search)' ] # uh...
	debug 1
</Plugin::PageCache>

The problem is, auto_cache needs to be an arrayref even though
there's only a single item in it, and I don't know how to
force Config::General to interpret it this way; if it's in the
docs, I'm missing it. Right now I get an error like

  Caught exception in engine "Can't use string ("[ '^(search)' ]")
  as an ARRAY ref while "strict refs" in use

I get the same error if I try to remove the brackets.

If I add another line like "auto_cache *", then things just
work, because with two identically named lines it assumes an
array, but I assume there has to be a way to make C::G read
this as an arrayref?

Thanks.
