So, like the enum.unique decorator that can be used when duplicate names should be an error,
I'm adding a new decorator to verify that a Flag has no missing aliased values that can be
used when the programmer thinks it's appropriate... but I have no idea what to call it.
Any nominations?
Thank you everyone for your ideas!  Instead of adding another single-purpose decorator, I'm toying with the idea of 
adding a general purpose decorator that accepts instructions.  Something along the lines of:
class EnumChecks(StrEnum):
         """
         various conditions to check an enumeration for
         """
         UNIQUE = "one name per value"
         CONTINUOUS = "no skipped values"
         DECOMPOSABLE_ALIASES = "flag aliases must have all bits named"
def verify(enumeration, *checks):
         if UNIQUE in checks:
             # ensure no duplicates
         if CONTINUOUS in checks:
             # ensure no missing values
         if DECOMPOSABLE_ALIASES in checks:
             # ensure all multi-flag aliases are composed of named flags
Thoughts?
