Perhaps this is a problem for a different issue, but pickling custom exceptions
fails when the exception gets more than one argument:
import pickle
class MultipleArgumentsError(Exception):
def __init__(self, a, b):
self.a = a
self.b = b
Exception.__init__(self, a)
pickle.loads(pickle.dumps(MultipleArgumentsError('a', 'b')))
this code produces the following error:
Traceback (most recent call last):
File "/tmp/multiple_arguments_exception.py", line 8, in <module>
pickle.loads(pickle.dumps(MultipleArgumentsError('a', 'b')))
File
"/usr/local/Cellar/python/2.7.13/Frameworks/Python.framework/Versions/2.7/lib/python2.7/pickle.py",
line 1388, in loads
return Unpickler(file).load()

File
