Bunch can't be displayed when flufl.enum is used

[s-celles]

Hello,

I did this

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from flufl.enum import Enum
from bunch import Bunch

class MyEnum(Enum):
    VAL1 = 1
    VAL2 = 2
    VAL3  = 3

b = Bunch()
b.x = 1
b.e = MyEnum.VAL1

print(b)

It raises

Traceback (most recent call last):

    print(b)

    raise RepresenterError("cannot represent an object: %s" % data)
yaml.representer.RepresenterError: cannot represent an object: MyEnum.VAL1

Any idea how to fix this ?

Kind regards
