            Bug ID: 420426
           Summary: Check and fixup for unused parameters
           Product: clazy
           Version: unspecified
          Platform: Other
                OS: Linux
            Status: REPORTED
          Severity: wishlist
          Priority: NOR
         Component: general
          Assignee: unassigned-bugs at kde.org

                CC: smartins at kde.org
  Target Milestone: ---

There is a check for "non-trivial" unused parameters. I would like to propose a
check and a fixup for all unused parameters.

Use case: We had a project in which we have a mock object mocking a wide API,
with lots of methods and lots of arguments for each of these. Most methods are
unimplemented, but they sprayed the compile output with warnings.

I commented out all the offending argument names, but it would have been nice
to be able to quickly apply a fixup to them instead. Fixup could be either the
commenting out, or perhaps inserting a Q_UNUSED(<parameter name>) at the top of
the implementation.
