[MESSAGES CONTROL]
# * locally-disabled, locally-enabled: If we disable or enable a message
#   locally, it's by design. There's no need to clutter the Pylint output
#   with this information.
# * logging-format-interpolation: Pylint warns about things like
#   ``log.info('...'.format(...))``. It insists on ``log.info('...', ...)``.
#   This is of minor utility (mainly a performance gain when there are
#   many messages that use formatting and are below the log level).
#   Some versions of Pylint (including 1.8, which is the version on
#   Ubuntu 18.04) only recognize old-style format strings using '%',
#   and complain about something like ``log.info('{}', foo)`` with
#   logging-too-many-args (Pylint supports new-style formatting if
#   declared globally with logging_format_style under [LOGGING] but
#   this requires Pylint >=2.2).
# * no-else-return: Allow the perfectly reasonable idiom
#    if condition1:
#        return value1
#    else:
#        return value2
# * unnecessary-pass: If we take the trouble of adding a line with "pass",
#   it's because we think the code is clearer that way.
