get_list() returns NoneValue's, not None's

[movermeyer]

Given the following pyhocon file:

single_value = null
list_value = [null]

And the following code:

from pyhocon import ConfigFactory
config = ConfigFactory.parse_file("test.conf")

single_value = config.get("single_value")
print single_value, single_value is None

list_value = config.get_list("list_value")[0]
print list_value, list_value is None

print single_value == list_value

You get as output:

None True
<pyhocon.config_tree.NoneValue object at 0xe20ad0> False
False

I expected both values to be Python's None.
