title: Python Selector (URL routing library), experience/opinions?
body: <p>Does anyone have opinions about or experience with <a href="https://github.com/lukearno/selector" rel="nofollow noreferrer">Python Selector</a>?  It looks great, but I'm a bit put off by its "Alpha" status on pypi and lack of unit tests.</p>
  
  <p>I mostly like that its simple, self contained, and pure WSGI.  All other url routers I've found assume I'm using django, or pylons, or paste, or pull in lots of other dependencies, or just don't let me create a simple <em>mapping</em> of url patterns to wsgi apps.  Really, all I want to do is:</p>
  
  <pre><code>mapper.add("/regex/{to}/{resource}", my_wsgi_app)
  mapper.add("/another/.*", other_wsgi_app)
  ...etc...
  </code></pre>
  
  <p>Anyways, has anyone used it before, or know of projects that have?</p>
