Fantastic breakdown of enums as a workaround for Python's lack of true constants. The point about silent typos with raw strings is something I ran into constantly when building a state machine last year, switching to IntEnum literally saved me from a debugging nightmare. One thing that caught my attention is how StrEnum auto-generates lowercase values, which is super conveniet for APIs expecting specific casings. Worth noting tho that enum comparisons can trip people up since identity checks work differently than with primitives.
