title: PyCharm type hinting for class/instance variables
body: <p>I have been trying this:</p>
  
  <pre><code>class Symbol:
      name: str
      board: str
      sector: str
  </code></pre>
  
  <p>for type hinting of class/instance variables.</p>
  
  <p>I do not get any errors, but PyCharm does not give me any warning when I violate the hinting, for example setting </p>
  
  <pre><code>self.name = 123
  </code></pre>
  
  <p>Yet, PyCharm otherwise gives me warnings, when I violate hinting of method signatures such as</p>
  
  <pre><code>def __init__(self, filename: str):
  </code></pre>
  
  <p>when I try to call the constructer and set filename to anything that is not str.</p>
  
  <p>Is it possible to get PyCharm to give warnings over type hinting for class/instance variables?</p>
