Given it returns an eternal object, and it's almost always used temporarily (for attribute lookup, string joining, etc.), it would seem more practical for it to return a borrowed reference. For purity reasons: all PyUnicodeFrom* functions return new references (most of them return actually new objects most of the time); having PyUnicodeFromId return a borrowed reference would break uniformity. I personally it difficult to remember which functions return borrowed references, and wish there were fewer of them in the API

I agree with this general sentiment. For PyUnicode_FromId, though, I think it makes sense to return a borrowed reference.

Antoine.
