A whitelist, if we go that route, should be on a per Enum basis -- so
class Planets(str, Enum):
PLUTO = 'it is too a planet!'
MERCURY = 'definitely a planet'
SATURN = 'darn big planet'
solar_mass = 82738273 # or some really big number
light_year = 1827499 # another really big number (of feet!)
def horrorscope(self, message):
return ('%s will be in retrograde... '
'don't communicate today.' % self)
and only PLUTO, MERCURY, and SATURN would be converted to enums.
