title: Can named arguments be used with Python enums?
body: <p>Example:</p>
  
  <pre><code>class Planet(Enum):
  
      MERCURY = (mass: 3.303e+23, radius: 2.4397e6)
  
      def __init__(self, mass, radius):
          self.mass = mass       # in kilograms
          self.radius = radius   # in meters
  </code></pre>
  
  <p>Ref: <a href="https://docs.python.org/3/library/enum.html#planet" rel="noreferrer">https://docs.python.org/3/library/enum.html#planet</a></p>
  
  <p>Why do I want to do this?  If there are a few primitive types (int, bool) in the constructor list, it would be nice to used named arguments.</p>
