&gt; Speed up AssignmentPattern parsing
&gt; 
&gt; I haven't run the full test suite, this isn't ready yet, but it does produce
&gt; a significant speedup for loading this page. Most real-world destructuring
&gt; patterns are probably not that big, so while those would still be slow, they
&gt; shouldn't be as noticeable.</span >

This seems like a good choice. You should add a similar test case to Joe's as a regression test. 

<span class="quote">&gt; PS, webkit-patch is failing to upload my patches today
&gt; (<a href="https://gist.github.com/caitp/27af5c48cd1758c65784">https://gist.github.com/caitp/27af5c48cd1758c65784</a> for a log), so this is
&gt; just the output from `git format-patch`, hope that's cool.</span >

We've been having server issues. As long as the patch applies, it doesn't matter how it's generated. Without webkit-patch, you will need to manually set flags for r?, cq?, and submitting it to EWS by clicking the button next to the attachment.</pre>
