This is a ticket to explore the possibility of adding support for Python 3.4+ enums to voluptuous.

So far it's possible to write:

import enum

from voluptuous import In, Schema

class MyEnum(enum.Enum):
    A = 'a'
    B = 'b'

s = Schema(In(item.value for item in MyEnum))
s('a')

but perhaps it would be nice if it could be written as the following?

s = Schema(In(MyEnum))

or:

s = Schema(MyEnum)
