CallableBool] has no hash function, membership test operations for sets do
not work:
{{{
from django.utils.deprecation import CallableTrue
assert CallableTrue in {True}
TypeError: unhashable type: 'CallableBool'
}}}
Adding a hash function solves this problem:
{{{
def __hash__(self):
return hash(self.value)
}}}
