title: Python 3.5 syntax using '@' to pass argument into function and PyLint
body: <p>I'm currently using the PySpice module for circuit sim. PySpice is using some syntax implemented in Python 3.5 that I've never seen before: <a href="https://pyspice.fabrice-salvaire.fr/api/PySpice/Unit.html" rel="nofollow noreferrer">https://pyspice.fabrice-salvaire.fr/api/PySpice/Unit.html</a> I'd like to find the Python reference for this syntax.</p>
  
  <p>Primarily, I'd like to get PyLint to recognize it.</p>
