Util::H2O will take this,
my $ref = { foo => $bar => 'baz' };
printf "%s\n", $ref->{'foo'}{$bar};
And let you do this:
use Util::H2O qw/h2o/;
my $ref = h2o -recurse, { foo => $bar => 'herp' };
printf "%s\n", $ref->foo->$bar;
If you use a lot hash references, it can remove a significant amount of typing and cruft simply by doing away with the curly braces. The reduction in typing and file size from these 2 characters quickly adds up.
enjoy!

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
