D7296: pycompat: kludge around pytype being confused by __new__

[indygreg (Gregory Szorc)]

indygreg added a comment.


  This one makes me sad because of potential performance regressions due to call overhead. I'd almost rather rip out Python 2 support rather than land this. But I could be convinced if pytypes is as cool as you say...
  
  Is there no way to annotate the types here without the call overhead? Could we do something like an `if False` trick to define a `def bytestr()` with the proper annotations? Surely there's got to be a way...
