C extensin for Variable#lax_parse

If we are trying to get the struct from something other than self, then we
should make sure to check the class of the object.  This util functions
make this easier.

+## Things we won't merge
+
+* Code which introduces considerable performance degrations
+* Code which touches performance critical parts of Liquid and comes without benchmarks
+* Features which are not important for most people (we want to keep the core Liquid code small and tidy)
+* Features which can easily be implemented on top of Liquid (for example as a custom filter or custom filesystem)
+* Code which comes without tests
+* Code which breaks existing tests
+
+## Workflow

+
+## Introduction
+
+Liquid is a template engine which was written with very specific requirements:
+
+* It has to have beautiful and simple markup. Template engines which don't produce good looking markup are no fun to use.
+* It needs to be non evaling and secure. Liquid templates are made so that users can edit them. You don't want to run code on your server which your users wrote.
+* It has to be stateless. Compile and render steps have to be separate so that the expensive parsing and compiling can be done once and later on you can just render it passing in a hash with local variables and objects.
+
+## Why you should use Liquid
+
+* You want to allow your users to edit the appearance of your application but don't want them to run **insecure code on your server**.
+* You want to render templates directly from the database.
+* You like smarty (PHP) style template engines.
+* You need a template engine which does HTML just as well as emails.
+* You don't like the markup of your current templating engine.
+
+## What does it look like?
+
+```html
+<ul id="products">
+  {% for product in products %}
+    <li>
+      <h2>{{ product.name }}</h2>
+      Only {{ product.price | price }}
+
+      {{ product.description | prettyprint | paragraph }}
+    </li>
+  {% endfor %}
+</ul>
+```
+
+## How to use Liquid
+
+Liquid supports a very simple API based around the Liquid::Template class.
+For standard use you can just pass it the content of a file and call render with a parameters hash.
+
+```ruby
+@template = Liquid::Template.parse("hi {{name}}") # Parses and compiles the template
+@template.render('name' => 'tobi')                # => "hi tobi"
+```
+
+### Error Modes
+
+Setting the error mode of Liquid lets you specify how strictly you want your templates to be interpreted.
+Normally the parser is very lax and will accept almost anything without error. Unfortunately this can make
+it very hard to debug and can lead to unexpected behaviour. 
+
+Liquid also comes with a stricter parser that can be used when editing templates to give better error messages
+when templates are invalid. You can enable this new parser like this:
+
+```ruby
+Liquid::Template.error_mode = :strict # Raises a SyntaxError when invalid syntax is used
+Liquid::Template.error_mode = :warn # Adds errors to template.errors but continues as normal
+Liquid::Template.error_mode = :lax # The default mode, accepts almost anything.
+```
+
+If you want to set the error mode only on specific templates you can pass `:error_mode` as an option to `parse`:
+```ruby
+Liquid::Template.parse(source, :error_mode => :strict)
+```
+This is useful for doing things like enabling strict mode only in the theme editor.
+
+It is recommended that you enable `:strict` or `:warn` mode on new apps to stop invalid templates from being created.
+It is also recommended that you use it in the template editors of existing apps to give editors better error messages.

       The Arbor Draft snowboard wouldn't exist if Polynesians hadn't figured out how to surf hundreds of years ago. But the Draft does exist, and it's here to bring your urban and park riding to a new level. The board's freaky Tiki design pays homage to culture that inspired snowboarding. It's designed to spin with ease, land smoothly, lock hook-free onto rails, and take the abuse of a pavement pounding or twelve. The Draft will pop off kickers with authority and carve solidly across the pipe. The Draft features targeted Koa wood die cuts inlayed into the deck that enhance the flex pattern. Now bow down to riding's ancestors.

       <p>Producing 170hp (125kW) and with a dry weight of just 169kg (372.6lb), the new 1198 S now incorporates more World Superbike technology than ever before by taking the 1198 motor and adding top-of-the-range suspension, lightweight chassis components and a true racing-style traction control system designed for road use.</p>
       <p>The high performance, fully adjustable 43mm Öhlins forks, which sport low friction titanium nitride-treated fork sliders, respond effortlessly to every imperfection in the tarmac. Beyond their advanced engineering solutions, one of the most important characteristics of Öhlins forks is their ability to communicate the condition and quality of the tyre-to-road contact patch, a feature that puts every rider in superior control. The suspension set-up at the rear is complemented with a fully adjustable Öhlins rear shock equipped with a ride enhancing top-out spring and mounted to a single-sided swingarm for outstanding drive and traction. The front-to-rear Öhlins package is completed with a control-enhancing adjustable steering damper.</p>
