#5519 enhancement new
Failure should become a new style class
|Reported by:||fijal||Owned by:|
According to glyph and exarkun, there is never ever a good reason to subclass a Failure, so it should not be a backwards incompatible change to make Failure a new style class.
Also, we can prohibit subclassing it in the first place *and* it makes pypy slightly faster.
