Comment:

 I think this is expected behaviour, that has a workaround.

 #15791 added a check for a `do_not_call_in_templates` attribute on a
 callable.

 Setting this to `True` in the example test case allows it to pass.

 This is documented in the
 [https://docs.djangoproject.com/en/2.0/ref/templates/api/#variables-and-
 lookups Variables and lookups] section of the Template API docs.

 Closing as a duplicate of #15791
