[issue42308] Add threading.__excepthook__ similar to sys.__excepthook__

[STINNER Victor]

STINNER Victor <vstinner at python.org> added the comment:

Can't you do that in your own hook? For example:

orig_hook = threading.excepthook
threading.excepthook = myhook

def myhook(args):
   try:
      ...
   except:
      print("too bad!")
      orig_hook(args)


I found one interesting usage of sys.__excepthook__ in code.InteractiveInterpreter:

        if sys.excepthook is sys.__excepthook__:
            lines = traceback.format_exception_only(type, value)
            self.write(''.join(lines))
        else:
            # If someone has set sys.excepthook, we let that take precedence
            # over self.write
            sys.excepthook(type, value, tb)

So it seems like sys.__excepthook__ is useful ;-)
