Tail-call optimization added to 6to5 compiler

I was literally complaining today about the fact that no-one seems to have yet implemented that part of the ES6 standard yet[1], and yet now here it is.<p>As someone chiefly interested in .js for it&#x27;s &#x27;functional curious&#x27; side, the new features in ES6 have me really excited.

Best part, from the actual commit[1]:<p><pre><code> Showing 24 changed files with 182 additions and 214 deletions. </code></pre> More lines <i>deleted</i> than added.<p>[1] <a href="https://github.com/6to5/6to5/pull/714/files" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;6to5&#x2F;6to5&#x2F;pull&#x2F;714&#x2F;files</a>

Available as of 3.5.0. Happy to answer any questions if anyone has any!

I wonder if this implementation idea is general enough that it could be added to clojure anr script.
