If a local variable is assigned, but not read after the assignment, that would be a nice Unnecessary Code warning, too.

private void currentWarning() {
	int x = 0;	// this generates the "Local variable is
			// never read" warning
}

private void proposedWarning() {
	int x = 0;
	if (x > 0)	// since we are using x here, there is no warning above;
		return;
	x = 7;		// this is where I propose a new warning, because we're
			// done with x already; setting its value is of no use.
}
