- What's a GOOD way?
- Am I reinventing the wheel?
- Are there well tested, fast, state of the art, builtin ways?
- Is something like line.decode('htmlentities') out there?
- Am I in conformity with relevant RFCs? (I'm hoping so ...)

Mainly a matter of style. When I'll be using the function in future
this way it's unambigously clear that there might have been
unconverted entities. But I don't have to deal with the details of how
this has been discovered. And may be I'd like to change the algorithm
in future? This way it's nicely encapsulated.
Have a nice day
