title: Get keys of an interface, in generics
body: <p>I have a function that uses generics. The generics in question is just <code>&lt;T extends anInterfaceName&gt;</code>. The problem is, in the function I need to get the keys of the interface used in T. After doing some research, i found <a href="http://github.com/kimamula/ts-transformer-keys" rel="nofollow noreferrer">this</a> module.</p>
  <p>Problem is, it doesn't work with generics. I can't seem to find anything that can help, is there anything that could do this? Is there a work around to this problem?</p>
