-# In D, enums are just that, enums. They're a group of named constants,
-# sometimes with a tag, sometimes anonymous.
-# In Python, Enums use the same syntax as class objects that derive from
-# the "Enum" base class, even though they are not normal python classes
-# and work as singletons anyway, but instead of using a different syntax,
-# Python instead decided to have a chapter in their docs about how Enums
-# are different from regular classes while looking exactly the same.
