Please use built-in enums

This is a very unusable implementation - namely because it requires a match/case or similar anti-pattern to be implemented as you've created a fairly whacky method of returning a string representation.

For example, if I simply want to record that the bit-rate mode of an MP3 was CBR - there's no easy way for me to just get CBR as you've forced the string representation to be BitrateMode.CBR. I have no idea why anyone would ever want the Enum class in their string representation and is very non-standard.

Either this, or please implement the standard .name and .value properties in normal Python enum to make this possible.

The implementation comes from a time before there was enum in the standard library. Switching to the built-in enum might be a breaking change in some way. But implementing the name and value properties makes sense to me.

I wouldn't call it "very non-standard". It is exactly what Python's enum.__str__ does as well:

from enum import Enum
Color = Enum('Color', ['RED', 'GREEN', 'BLUE'])
str(Color.RED)  # This is "Color.RED"
