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?
