title: Is Hash Rocket deprecated?
body: <p>The well-cited <a href="http://web.archive.org/web/20130909062027/http://peepcode.com/blog/2011/rip-ruby-hash-rocket-syntax" rel="noreferrer">RIP Hash rocket post</a> would seem to imply the Hash Rocket syntax (<code>:foo =&gt; "bar"</code>) is deprecated in favor of the new-to-Ruby JSON-style hash (<code>foo: "bar"</code>), but I can't find any definitive reference stating the Hash Rocket form is actually deprecated/unadvised as of Ruby 1.9.</p>
