You could file an enhancement request in Bugzilla requesting that the

Personally I think this is the way to go. The variable is implicitly
used, and the warning should reflect that.
If C++ had allowed for(int:range) in addition to for(int i:range), like
you can abstain from naming function arguments, the warning would have
made more sense. As it is, I agree the warning should go, although I don't
know why you say the variable is implicitly used.
