    This is useful for defeating flake warnings.
    Call this function to use values that really should be ignored.
    This is intended as a declaration that variables are intentionally ignored,
    but no enforcement of that is done. Some sample uses:

    def foo(x, y):
        ignored(x, y)  # so flake8 won't complain about x and y being unused.
        return 3
