"The value changed at ++index is never used"

Ok, Ive run this past several colleagues here, and we all think that this is a bad call :

Code such as :

foo.bar( ++index );

being flagged as a warning with the following message: "The changed at ++index is never used"

we think is incorrect.

The value changed at ++index is used.

Im also aware that this was discussed a couple of weeks back, but nothing seemed to come of that.

So, can we at least get a config option to disable this warning, or, better (as far as we see), get this fixed so that such usage of the pre-increment operator is not flagged as a warning.
