Example enumeration:

class Seasons(Enum): SPRING = 1 SUMMER = 2 AUTUMN = 3 WINTER = 4

 days_in_year = 365

 @property
 def avg_temp(self):
     return (75, 92, 66, 33)[int(self)+1] # enums are 1-based

Definite Issues:

• should enum items be of the type of the Enum class? (i.e. type(SPRING) is Seasons)

• should an enum item be selectable via call instead of getitem (i.e. Seasons(3) is AUTUMN)

• should days_in_year be enumerated?

• should avg_temp be enumerated?

• for the above two, how should they be included/excluded?
