3.1
not sure how common a problem that is but one could make an experiment before
implementing a check.

Detect cycles of unused private members. That is, currently the compiler flags
as unused any private member that is not read/called from *anywhere*.
But the member is just as dead if it is only called/read from only members that
are not reachable from any non-private member.

example of missed dead code (both methods are dead code - but the compiler does
not complain):

class A{
	private void foo(){
		bar();
	}

	private void bar() {
		foo();
	}
}
