The +problems with it are: + +* It makes it so one can't jump into the middle of a file and know whether a bare literal string is + a byte string or text string. The programmer has to first check the top of the file to see if the + import is there. +* It removes the ability to define native strings (a string which should be a byte string on python2 + and a text string on python3) via a string literal. +* It makes for more context switching. A programmer could be reading one file which has + `unicode_literals` and know that bare string literals are text strings but then switch to another + file (perhaps tracing program execution into a third party library) and have to switch their + understanding of what bare string literals are. + diff --git a/lib/ansible/plugins/lookup/mongodb.py b/lib/ansible/plugins/lookup/mongodb.py index dff4a7bbec..6f410aeb53 100644 --- a/lib/ansible/plugins/lookup/mongodb.py +++ b/lib/ansible/plugins/lookup/mongodb.py @@ -88,7 +88,6 @@ EXAMPLES: ''' from __future__ import (absolute_import, division, print_function) -from __future__ import unicode_literals from ansible.module_utils.six import string_types, integer_types import datetime @@ -120,7 +119,7 @@ class LookupModule(LookupBase): return sort_parameter if not isinstance(sort_parameter, list): - raise AnsibleError("Error.
